My shop has used Bullet Proof Diesel… My shop has used Bullet Proof Diesel for a few years now, and we're consistently impressed with their quality products. We've used their air cooled oil cooler kits, FICM's, egr coolers etc. Our customers are happy with the efficiency and effectiveness of everything we get from Bullet Proof, so we'll continue to use them.

Bad Communications, failed performance and loss of a repeat customer’s shop The sales team was 5-stars. The shipping team was extremely problematic. We have ordered in the past with minor issues. This most recent event was adversarial. It was a $3000+ Order that was returned by BulletProof. If I was an owner, I would terminate those involved. If the owner endorsed such activity, then itnis best to buy elsewhere. We repaired the last unit from our regular vendors to complete the project. He understood and was happy with the reduced parts cost. We would deter future clients from purchasing here and only use when a client demands such. There are too many spots locally and online to buy $3000 parts orders. DieselTech RON would not approve!!!

Everything Ive bought from them works Everything Ive bought from them works! They provide exactly what they advertise. If you are questioning whether or not to do business here, do yourself a favor, and commit. It may be more expensive than some other alternative that may exist, but months or years from now, you will understand the real value of what they are offering. What they are really selling, is confidence.. and I for one am a believer!

Super Happy with your product and… Super Happy with your product and lifetime warranty of your products. OEM Ford Products don’t even carry a two year warranty. Bulletproof Diesel has made my 6.0 liter a happy running engine. Thank you for everything. Shout out to Andrew Presley for great service. Thank you to Ledoms Diesel Performance and Repair for using Bulletproof products.

I bought the 58v ficm power supply… I bought the 58v ficm power supply after experiencing no start issues. The difference between the stock unit is amazing. Sturdier board and I am even seeing an increase in fuel mileage and throttle responce. I would highly recommend this product to any ford 6.0 owner.
