Best spark plugs for 88 Jeep with 4.0L?
« on: November 27, 2007, 12:57:42 AM »
So Im getting ready to do a spring tune up and right now I have Bosch Platinum 4 plugs which are HORRIBLE, I know I know. Anyways what is the best replacement for the 4.0L engine that will give me the best performance while not shocking my wallet?

The Bosch platinum 4 is nothing but junk and lies.  The stock champions are the winners.
