It’s a proven fact that OEM head bolts are the weak link in a diesel engine; especially if the engine has been modified. Diesel engines are all assembled using “Torque To Yield” bolts and any increases in combustion pressure can lead to problems like blown head gaskets or catastrophic engine failure. ARP's Diesel Head Stud Kits are designed for higher clamping loads and much safer and stronger than OEM. They are available in several different strength materials to safely handle applications from performance street to all-out competition.

Great wheel studs.

Just what I wanted

Was looking for a bigger intercooler for my 2016 F-150 2.7 ecoboost. Horsepower direct definitely had the best price by over $100 cheaper than everywhere else. This was the biggest one I could find so I got it. Install was alright. The way it mounts is a pain but I eventually got it done. Air intake temps are right around/a few degrees above the outside temp when driving. Seems to be working as it should.

works perfectly

Product works and installs exactly how it's supposed to!

Fantastic service!

Fast and very helpful staff will definitely order from again and recommend to others.

Install time 1.5 hours but good quality

Install time 1.5 hours, but quality is good and looks professional. It took two people when it came to disconnecting the air snorkel to turbo to align snorkel and clamp. Nice product...
