We are proud to be a preferred installer for bullletproof . We opened our shop back in 2011 and have been installing there components ever since . Saves the 6.0 before bulletproof came along they were not a permeant fix . Like a said me and all of my 6.0 customers are happy bulletproof took the time to come out with the parts that keep failing over and over thanks again

EGR Cooler

The stock egr cooler gave out while coming home from a camping trip. Decided it was time to upgrade my truck not just repair it. While I had the top of the engine apart anyway I did the BPD heavy duty oil cooler, BPD water pump and egr valve. John was awesome and a big help figuring out all the details needed to make sure I was getting the correct parts for my year truck. The instructions in the oil cooler kit are great and easy to follow. It’s step by step and they include pictures and exploded diagrams also. This was my first time diving this deep into any diesel but BPD made it easy. The parts are manufactured very well, it’s a shame you don’t get to see the quality when the engine and all other parts are back in place. I am a very satisfied customer and will be returning for the FICM at a later time.

Good Product

Replaced this part as a component of my BulletProof upgrade. Installs easy (once the engine is torn down) and the return of the core went smoothly.

Great product!

Had an oil cooler go bad in my 6.0.
While the Local Ford dealership was repairing that, I had them install the. Bullet Proof EGR cooler. Ford had no problem installing it. It was only a matter of time before the factory one would go out so had it replaced while they were in there.
