UPC: 841788114592
This item is Sinister Diesel has reinvented the Exhaust Gas Recirculation (EGR) cooler with this great new model with the same fit as your factory EGR cooler. If you're tired of clogging in your diesel engine's EGR cooler, or if you just want to prevent future headaches, Sinister Diesel's parent company, Sinister Manufacturing, has created an EGR cooler that looks and fits like your factory model, but works way better than your stock cooler ever did! Our less-restrictive design reduces clogging by replacing the narrow thin walled inner tubes with high-flow stainless steel tubing for improved reliability and durability. Manufactured with high-quality TIG welds, each EGR cooler is pressure tested and is guaranteed to protect against leakage. There's no need to do any sort of modification, as our EGR coolers are direct drop in replacements. Another major concern with the factory EGR Cooler is that when it cracks, it will start forcing coolant into the intake manifold. Once you get coolant in the intake system, it will get fed into the combustion chamber, which usually results in a blown head gasket, or hydro-locked motor. When you purchase one of our upgraded EGR coolers, you're being proactive and taking the necessary steps to protect your truck. Don't break the bank, protect your investment and don't waste anymore time or money on factory EGR coolers Features: Construction - Stainless Steel, Product Design - Full TIG welds and pressure tested, Performance Notes - Improved exhaust gas flow, Kit Includes - (1) Sinister Diesel EGR Cooler, Special Note - Does not require removal of intake manifoldFAQ's Q: Will this trip my check engine light?, A: All of our Sinister Diesel EGR coolers are designed to work with your factory equipment and programming. These units will not trip your check engine light.

Came based on a work buddies recommendation. I was late by 30 minutes, confused my appointment time. But, 10/10 would come back. Came for a Downpipe and midpipe install. Not only was the gentleman accommodating, He ran into some issues, staff helped me out and pointed me into the right direction and got me going! They got my business and wouldn’t go anywhere else again!

Absolutely love the customer service that you get with Speedzone Performance! All my questions are always answered in such a timely manner and this a big PLUS because I live out of Florida and for them to be on top of answering all my questions in such a way means a lot. Thank you all for the amazing customer service.

My favorite place to go for anything car related, they have anything you could imagine & more. The people who work here are the coolest and most helpful people I’ve yet to meet at a car shop. They also don’t try to force sales on you and they genuinely help you with what you’re looking for, 100/10 shop!
