Re: Need Advice on 4 Cyl Jeep
I own a 97 TJ with the 4 cyl and a 00 TJ with the 6 cyl. I put a K&N FIPK (fuel injection performance kit) on both engines. The kit is a tube with a cone air filter that replaces the stock air filter box. This made a very big difference on both engines. The best way to describe it is that it is like pulling a sock out of your throat. I run 31x10.50x15 on the 4 cyl and prior to the K&N it had a hard time holding 65 going down the freeway. After the K&N it not only held 65 but it would accelerate fairly well even up hills. If you can hold out/afford the 6 cyl you won't be disappointed. If not, don't buy a 4 cyl with automatic tranny, it makes the Jeep even worse. (I also own a Grand Cherokee Limited with the 8 cyl and put the K&N on it, I swear by the things. And no I am not a salesman for K&N). Airaide also makes a kit that is less expensive. As far as problems go the 4 cyl has 68k on it and the only things that went bad were the radiator top tank came unsealed (mainly because they are plastic) and the coil went bad. Other than that both have been real dependable. Good luck!
