Howdy yall,
unfortunately im kinda new to the forum and cant seem to find any posts relating to 3.7 engine upgrades.

My question is are there any turbo chargers for the 3.7 engines and can anybody give me any reviews on the k&N 57 series air intake?

 

These trucks have a small, if non-existen aftermarket. Even more so for the 3.7.
Some other guys may have more input for you. I myself have a 3.7 but only a CAI on it.

 

I made my own intake. It was a lot cheaper than buying a K&N kit. I also did the E-fan. Those both made a difference. But then again, its hard for me to tell with 33" tires, factory gearing, and living at 6000ft in elevation.

I have heard that the 3.7L pistons are not very stout, thus adding additional cyclinder pressures (boost) is not advised with factory pistons. I think a few jeep guys tried superchargers and found this out.

The only other two engine mods I will do are exhaust and gearing.

 

And for the truck a leveling kit always does the trick. I want to make a CAI for my 3.7. I think it looks cooler than a K&N. I also have a flowmaster exhaust turned down before my rear diff. Other than that just sparkplugs.

 

**** i thought it was hard for the 4.7 never thought what would happen with a 3.7, but donkey i believe the part number is the smae for the v6 and v8 piston? or i may be wrong....ill check.... it out

 

Cai are even on ebay, got mine works great. About 50 dollars, I think it looks better than home made ones.

 

Thanks for the input now as far as CAIs are concerned im pretty happy with this one
