WrenchConnected is an independent installation marketplace operating in partnership with Diesel Power Products.
After checkout, we route your vehicle info and part SKU to verified installation shops near you. Local installers review the job and submit competitive bids; you pick the shop you want based on price, reviews, and availability. Your name and email stay private until you select an installer.
You pay for the bid from your preferred shop. The full amount is shown before you confirm — installers cannot add charges without your written consent. Payments are processed securely by Stripe.
During bidding, shops see only your service ZIP code, vehicle year/make/model, and the part SKU — not your name, email, or address. Only the shop you select receives your contact details after payment. We never sell your personal information.

Sinister stands for everything diesel and they have made a name for themselves manufacturing some of the highest quality diesel engine components in the industry. The Sinister Diesel brand was born out of an idea from the founders while working on one of their own trucks. What if they started their own diesel performance business manufacturing and selling high quality air intake, fuel, and engine components? That idea transpired into the Sinisterl Diesel we know today. In order to make sure that when you popped the hood, you could easily distinguish a œSinister branded part from other companies, nearly everything they manufacture is coated in their trademarked œSinister Blue. Whether you drive a Cummins, Powerstroke, or Duramax, they can outfit your entire truck with cold air intakes, fuel tank sumps, oil filtration, regulated fuel return kits, and so much more. If you're looking for quality performance parts at a great price, look no further than Sinister!

"This is no better then the oil cooler I had it's bad when a company gotta lie to sell something my coolant and oil are 15 degrees different"
"I swapped out my oil cooler while installing head studs as it was easy to get to. There was nothing wrong with my old one, 10 deg deltas max while pulling, more of a preventative maintenance. Bad move. On start up I had 15 deg deltas around town and pulling I see 28-30deg deltas consistently. I have run this cooler about 5,000 miles sitting on pins and needles watching oil temps everywhere I go. I will have it in the shop later this week putting OEM back in. Waste of time and money."
"After much research I purchased this oil cooler. It was my understanding that my oil and coolant temp would be within the 10 degree differential range. . I am not seeing those results. . Most times, I have a 14 degree difference in the oil and coolant temps. . I am disappointed with this product."
"I Installed this cooler and now i stay with in ten degrees with oil and coolant."
