Frequently Asked Questions

Will a cold air intake void my Jeep SRT8 warranty?

In general, a cold air intake does not automatically void your warranty. However, if the intake causes a failure (e.g., MAF sensor damage from over-oiling), the repair may not be covered. The Magnuson-Moss Warranty Act protects consumers, but the dealer must prove the aftermarket part caused the issue. For peace of mind, choose a CARB-legal intake and keep your OEM parts.

Do I need a tune after installing a cold air intake on my SRT8?

Most modern SRT8s can adapt to a cold air intake without a tune, as the ECU can adjust fuel trims within limits. However, a tune can optimize the gains and is recommended for maximum performance. Some intakes may trigger a check engine light if the MAF sensor is affected by oil. A tune can also improve throttle response and shift points.

How much horsepower can I expect from a cold air intake on a Jeep SRT8?

Based on manufacturer claims and owner dyno results, most cold air intakes for the SRT8 provide gains of 10-20 horsepower at the wheels. The actual gain depends on the intake design, ambient conditions, and whether a tune is used. Sealed systems with direct cold air ducts tend to perform better than open-element designs.

What is the difference between oiled and dry filters?

Oiled cotton filters (like K&N) are washable and reusable, but require careful re-oiling to avoid MAF contamination. Dry synthetic filters (like AFE Pro Dry S) are oil-free and easier to clean, but may need replacement after several washes. Oiled filters generally flow more air but have slightly lower filtration efficiency. Dry filters offer consistent filtration and are less messy.

Are cold air intakes legal in California for the Jeep SRT8?

California requires aftermarket intakes to have a CARB Executive Order (EO) number to be legal. Some intakes like K&N 71-3074 and Mopar 82215139AB are CARB exempt. Others may not be approved and could cause smog test failure. Always check for a CARB EO if you live in California or other states that follow CARB rules.
