Power mods for the I-5

[wpage]

Had some improvement in performance by adding S&B Filter replacing stock air filter. In addition cut a 3" hole and inserted a aluminum flex tube running out under thru front starboard wheelwell to hole in bumper as a natural ram with a common air conditioner filter.
My estimate 5-10% gain in torque and hp. Impact on warrentee after cutting hole in air plenum is unknown!

Ram Air on a HUMMER?

Yea and engineered by hacksaw. No need to ask the dealer about warranty coverage. More noise than horsepower gain is guaranteed.

Nots not a good idea if your going through water

Ram air + water = blown moter


I dont have the factory ram air on my 68 442 so I made one and have two 3 inch hoses running down under the bumper(used 2 wet vac attachments for ducts at bumper and metal elbows from home depot at the air cleaner).
