1. PhatFabrications DD15 EGR Cooler Delete Kit: Top Pick
In our evaluation, the PhatFabrications kit stood out for its precise laser-cut T304 stainless steel construction. Owner feedback consistently notes that the block-off plates and gaskets align perfectly with the DD15 engine, reducing installation time. The kit is designed to keep the turbo and exhaust system in their original positions, which helps maintain engine balance.
However, this kit is not the most budget-friendly option. Some owners reported that the included gaskets could be thicker for a more secure seal. If you are looking for a premium, no-compromise kit and are willing to pay a bit more, this is our top recommendation. Skip this if you need a low-cost solution or are not confident in your mechanical skills.
- Precision laser-cut T304 stainless steel components resist corrosion and cracking
- Includes all necessary gaskets and block-off plates for a complete install
- Designed to maintain factory turbo and exhaust system alignment
Pros: Excellent fitment with no modification required; High-quality materials and welds
Cons: Higher price point compared to some competitors
2. Sinister Diesel DD15 EGR Delete Kit: Runner Up
Sinister Diesel offers a well-rounded delete kit that balances performance and cost. The aluminized steel with ceramic coating is designed to withstand high exhaust temperatures, and the kit includes all necessary hardware. Owner feedback indicates that the installation is straightforward for those with moderate mechanical experience.
On the downside, a few users noted that the block-off plates required slight filing to fit perfectly. This kit is a solid choice for budget-conscious buyers who still want reliable performance. However, if you want a true bolt-on experience without any adjustments, you might prefer the PhatFabrications kit.
- Aluminized steel construction with a ceramic coating for heat resistance
- Complete kit with all necessary hardware and block-off plates
- Designed for a direct bolt-on installation
Pros: Good value for the price; Ceramic coating helps with heat management
Cons: Some owners reported minor fitment adjustments needed
3. Flo-Pro Performance DD15 EGR Cooler Delete: Best Value
Flo-Pro Performance delivers a budget-friendly delete kit that still meets basic requirements. The mild steel with black powder coat offers decent durability, and the included stainless steel hardware is a nice touch. Many owners found this kit to be a good entry-level option for those wanting to delete the EGR cooler without spending a lot.
However, the powder coat is prone to chipping, and the mild steel is not as rust-resistant as stainless steel. This kit is best for owners in dry climates or those who plan to coat the parts themselves. Skip this if you need maximum corrosion resistance or plan to keep the vehicle for many years.
- Mild steel construction with a durable black powder coat finish
- Comes with high-temperature gaskets and stainless steel hardware
- Affordable option without sacrificing essential features
Pros: Very competitive price; Includes stainless steel hardware to prevent rust
Cons: Powder coat may chip over time; Not as corrosion-resistant as stainless steel
4. BD Diesel DD15 EGR Delete Kit: Premium Build
BD Diesel is known for heavy-duty components, and their DD15 delete kit is no exception. The mandrel-bent T304 stainless steel tubing and CNC-machined flanges provide a high-quality seal and optimal exhaust flow. Owner feedback highlights the excellent fitment and durability, even in demanding applications.
The main drawback is the higher cost, which may not be justified for casual users. This kit is ideal for those who want the best materials and are willing to pay for longevity. If you are on a tight budget or only need a temporary solution, this is not the kit for you.
- Mandrel-bent T304 stainless steel tubing for smooth flow
- CNC-machined flanges ensure a precise seal
- Includes all gaskets and hardware for a complete install
Pros: Exceptional build quality and fit; Mandrel bends reduce flow restriction
Cons: Premium price may be overkill for some
5. Mountain Performance DD15 EGR Cooler Delete: Budget Pick
Mountain Performance offers the most affordable option for those who need a basic delete kit. The mild steel and painted finish are adequate for short-term use or in dry climates. Owner feedback suggests that the kit generally works, but some reported that the block-off plates needed grinding to fit properly.
This kit is not for long-term reliability or harsh environments. The paint can peel, leading to rust. We recommend this only for budget-constrained buyers who are comfortable with modifications and plan to upgrade later. Skip this if you want a durable, long-lasting solution.
- Economical mild steel construction with a basic paint finish
- Includes block-off plates and necessary bolts
- Designed as a no-frills solution
Pros: Lowest price among reviewed kits; Simple design works for basic delete needs
Cons: Paint may peel; not recommended for rust-prone areas; Fitment may require minor adjustments
6. Pure Performance Diesel DD15 EGR Delete: Easy Install
Pure Performance Diesel focuses on ease of installation. The pre-assembled sections and clear instructions make this kit a good choice for first-time installers. The 304 stainless steel offers decent corrosion resistance, and many owners appreciated the time saved during installation.
However, a few users reported that the flanges felt thinner than expected, which could affect long-term durability. This kit is best for those who prioritize a straightforward install over absolute ruggedness. Skip this if you need maximum strength or plan to subject the kit to extreme conditions.
- Pre-assembled sections reduce installation time
- 304 stainless steel for good corrosion resistance
- Includes detailed instructions and all gaskets
Pros: Simpler installation than most kits; Good instructions for DIYers
Cons: Some owners noted thin metal on flanges; Not as robust as thicker-walled kits
7. Diesel Innovations DD15 EGR Cooler Delete: Heavy Duty
Diesel Innovations targets the heavy-duty market with a thick stainless steel kit and reinforced welds. This kit is built to withstand high stress and is a favorite among owners who push their trucks hard. Owner feedback praises the durability and lack of leaks even after extended use.
The trade-off is extra weight and a higher price. This kit is overkill for a daily driver used for light hauling. It is best suited for those with modified engines or who demand maximum strength. Skip this if you want a lightweight or budget-friendly option.
- Heavy-gauge T304 stainless steel for maximum durability
- Reinforced welds at stress points
- Includes heavy-duty gaskets and hardware
Pros: Very robust construction; Designed for high-performance applications
Cons: Heavier than other kits, may add weight; Higher price point
Frequently Asked Questions
Is it legal to delete the EGR cooler on a DD15 engine?
No, removing the EGR cooler is illegal for on-road use in most areas because it disables emissions control systems. Off-road and competition use only. Check local laws before purchasing.
Will an EGR cooler delete void my engine warranty?
Yes, deleting the EGR cooler will almost certainly void the manufacturer’s warranty on the engine and emissions system. Some aftermarket warranties may also be affected.
Do I need a tuner or programmer after installing a delete kit?
Yes, to avoid check engine lights and performance issues, you will need a tuner or programmer to disable the EGR system in the engine control module (ECM). Many kits recommend a specific tuner.
