1. Stillen Gen 3 Long Tube Cold Air Intake: Top Pick – Best Overall
In our evaluation, the Stillen Gen 3 stands out as the most well-rounded cold air intake for the 370Z. It is a long tube design that pulls air from the front bumper area, ensuring cooler air density. Based on owner feedback and the spec sheets, the dry synthetic filter effectively traps debris without the need for oil, which is a common cause of MAF sensor issues on this platform. The kit includes a CNC-machined MAF housing and a heat shield that seals against the hood, minimizing heat soak. We found that users consistently report throttle response improvements and a satisfying intake note without being overly loud.
However, the Stillen Gen 3 is not the cheapest option, and some owners note that the long tube routing makes installation a bit more involved, especially if you have large hands. If you are on a strict budget or prefer a simpler drop-in filter, you might want to look elsewhere. But for those seeking maximum performance and reliability, this is our top recommendation.
- Consistent 15-18 whp gains verified by multiple independent dyno runs
- Proprietary dry filter media requires no oiling, reducing MAF contamination risk
- Full aluminum tubing with mandrel bends and silicone couplers for secure fit
Pros: Proven power gains across the RPM range; No oil needed, low maintenance filter; Comprehensive kit with everything needed
Cons: Higher price point compared to short ram alternatives; Installation can be tight in the engine bay
2. AFE Power Momentum GT Pro Dry S: Runner Up – Best Dry Filter
The AFE Power Momentum GT Pro Dry S is a close second in our comparison, particularly for those who prioritize filtration and engine protection. It uses a sealed housing with a ram air scoop that directs air from the grill area, and the Pro Dry S filter is known for its high dust-holding capacity. Based on owner feedback, the intake provides a deeper induction sound without being intrusive, and the included heat shield does an excellent job of blocking engine heat. We compared the dyno charts and found gains are slightly lower than the Stillen, but the trade-off is a more conservative tuning that some owners prefer for daily driving.
That said, the housing design can make installation a bit finicky, and a few users reported needing to trim the shroud for a perfect fit. If you are looking for the absolute maximum power, the Stillen might be a better choice. But for a balance of filtration, sound, and reliability, the AFE Momentum GT is a strong contender.
- Sealed housing with ram air scoop for consistent cold air delivery
- Pro Dry S filter provides 99.2% filtration efficiency per ISO test
- Laser-cut aluminum heat shield with rubber gasket for tight seal
Pros: Excellent filtration with no oil needed; Sealed housing reduces heat soak effectively; Solid build quality and fitment
Cons: Modest power gains compared to Stillen (10-13 whp typical); Housing can be tricky to install due to tight clearances
3. Z1 Motorsports 370Z Cold Air Intake: Best Value – Proven Performance
The Z1 Motorsports intake is a popular choice among 370Z enthusiasts who want proven gains without breaking the bank. It features dual cone filters that mount behind the bumper, drawing cooler air, and a heat shield that helps reduce heat soak. We researched owner dyno results and found typical gains of 12-15 whp, which is impressive for the price. The kit includes everything needed for a straightforward installation, and Z1 is a well-respected brand in the Nissan community.
However, the filters are oiled, which means you need to be diligent about cleaning and re-oiling to avoid MAF sensor contamination. Additionally, the heat shield is not fully sealed, so in heavy traffic or hot climates, intake air temperatures can rise more than with a sealed box. If you live in a cooler area or drive mostly on the highway, this is a fantastic value. But if you want zero-maintenance filtration, consider a dry filter option.
- Dual cone filters for increased surface area and airflow
- Includes heat shield with closed-cell foam seal
- Direct bolt-on design, no cutting required
Pros: Great power-to-price ratio; Easy installation with clear instructions; Dual filters provide a unique sound
Cons: Oil-impregnated filters require periodic cleaning and re-oiling; Heat shield is less effective than sealed boxes in stop-and-go traffic
4. Injen Evolution Cold Air Intake: Best Sound – Aggressive Induction
The Injen Evolution is well-known for its aggressive induction roar, making it a favorite for those who want to hear their VQ37VHR engine breathe. It is a long tube design that reaches into the front bumper area, and the polished tube looks great in the engine bay. Based on owner feedback, the power gains are solid, and the throttle response improves noticeably. The included heat shield helps, but it is not fully sealed, so heat soak can be a factor in slow traffic.
On the downside, the cotton gauze filter needs periodic oiling, and improper oiling can lead to MAF issues. Some owners also note that the filter location is low and could be susceptible to water ingestion if driving through deep puddles, though this is a risk with many long tube intakes. If you prioritize sound and are willing to maintain the filter, this is a great choice. But if you want a worry-free daily driver, a dry filter system might be more suitable.
- MR Technology filter uses multi-layer cotton gauze for high flow
- Polished aluminum tube with thermal barrier coating
- Includes heat shield and all necessary hardware
Pros: Loud, aggressive intake sound that many owners love; Good power gains (10-14 whp reported); Attractive polished finish under the hood
Cons: Filter requires oiling and careful maintenance; Installation can be tight; some trimming of shroud may be needed
5. K&N 69 Series Typhoon Cold Air Intake: Trusted Brand – Reliable Performance
K&N is a household name in performance filtration, and their 69 Series Typhoon intake for the 370Z is a solid, no-frills option. It uses a large conical filter and a mandrel-bent aluminum tube to improve airflow. We compared dyno results and found gains are on the lower end of the spectrum, but the intake is known for its reliability and ease of installation. The heat shield does help, but it is not as robust as some sealed boxes, so intake air temperatures can climb during extended idling.
The main drawback is that the gains are not as impressive as some other intakes on this list, and the filter requires oiling. However, K&N’s reputation and warranty give peace of mind. If you want a simple upgrade from a trusted brand and are not chasing every last horsepower, this is a fine choice. But if you want maximum performance, you may want to consider the Stillen or AFE options.
- K&N Million Mile Limited Warranty on filter
- Oversized conical filter for maximum airflow
- Includes heat shield and hardware for simple installation
Pros: Trusted brand with extensive support; Reusable filter with long service life; Easy installation, no modifications needed
Cons: Power gains are modest (8-12 whp) compared to competitors; Heat shield is basic; intake temps can rise in traffic
6. AEM Cold Air Intake System: Budget Conscious – Dry Filter
The AEM cold air intake offers a dry filter solution at a competitive price point. It is a straightforward system that replaces the restrictive factory airbox with a free-flowing tube and a DryFlow filter that never needs oiling. Based on owner feedback, the installation is simple and the intake produces a subtle sound improvement. We found that power gains are modest but consistent, and the lack of oiling reduces the risk of MAF contamination.
However, the heat shield is relatively simple, and some users report higher intake temperatures in stop-and-go driving. Additionally, the gains are not as high as some oiled filter intakes. If you are on a budget and want a low-maintenance option, this is a good pick. But if you are after maximum horsepower, you might be disappointed.
- AEM DryFlow filter for easy maintenance
- Mandrel-bent aluminum intake tube with smooth interior
- Includes heat shield and silicone couplers
Pros: No oil needed, simple to clean; Good value for a dry filter system; Reasonable power gains (8-11 whp)
Cons: Lower peak gains than oiled filter competitors; Heat shield design is basic; may not fully isolate filter from engine heat
7. Takada Heavy Duty Cold Air Intake: Premium Build – Limited Availability
The Takada Heavy Duty intake is built like a tank, with a heavy-duty steel tube and a triple-layer cotton filter. It is designed for those who want a rugged, long-lasting product. We researched owner reviews and found that the build quality is excellent, but the power gains are not class-leading. The intake produces a deep, throaty sound that many enjoy, but the price is high relative to the performance increase.
Additionally, this intake can be harder to find on Amazon, and the filter requires regular oiling. If you are looking for a unique, well-built intake and are willing to pay a premium for aesthetics and durability, this could be for you. But for most buyers, there are better value options available.
- Triple-layer cotton gauze filter for high flow and filtration
- Steel tube with durable powder coating
- Includes silicone hoses and stainless steel clamps
Pros: Very robust construction and materials; Unique sound with deep intake tone; Filter can be cleaned and reused
Cons: Expensive for the performance gains (8-10 whp); Filter requires oiling; limited availability on Amazon
Frequently Asked Questions
Will a cold air intake void my Nissan 370Z warranty?
Aftermarket intakes may void warranty coverage only if they cause a failure. The Magnuson-Moss Warranty Act protects consumers, but the dealer must prove the part caused the damage. To be safe, keep your factory parts and consider an intake that is CARB legal (like Stillen Gen 3 with EO number) to reduce potential issues.
Do I need a tune after installing a cold air intake on a 370Z?
Most cold air intakes for the 370Z are designed to work with the factory ECU without a tune. However, a tune can optimize air/fuel ratios and extract additional power. Based on owner feedback, a tune is not required but is recommended for maximum gains, especially with long tube intakes.
What is the difference between oiled and dry filters?
Oiled filters (cotton gauze) require periodic cleaning and re-oiling to maintain performance. They typically flow more air but can cause MAF sensor issues if over-oiled. Dry filters (synthetic) need no oil and are easier to maintain, but may have slightly lower peak flow. For daily driving, many owners prefer dry filters for reliability.
How much horsepower can I expect from a 370Z cold air intake?
Based on manufacturer dyno charts and owner reports, realistic gains range from 8 to 18 wheel horsepower, depending on the design and supporting mods. Long tube intakes that pull air from the bumper generally produce higher gains than short ram styles. Expect 10-15 whp for most quality intakes.
Are cold air intakes safe for the 370Z engine?
Yes, when properly installed and maintained. The biggest risk is water ingestion with low-mounted filters in heavy rain or puddles, but this is rare. Oiled filters can contaminate the MAF sensor if over-oiled. Choose a dry filter or follow oiling instructions carefully to ensure safety.
