tune up questions

i have a 1994 4.0L and i want to give it a tune up. but i have read on here a couple of times that our jeeps only like certain spark plugs, wires, and what not.

can you guys recommend me some : spark plugs, wires, cap and rotor, and fuel filter.

I don't know if the Jeep "likes" certain plugs and wires. I think the owners do!

In last tune-up I left previous owner's brand new hi-capacity/hi-perf plug wires in and threw his NGK plugs out. I don't like NGK's. I don't like Bosch either.

I like Auotlite or Champion...but it all goes to show you...the next post will be someone who swears by Bosch's...

You have to tune-up with instinct. No one on the planet knows your rig better than you do. When you notice performance suffering sometimes you can trace it back to a product...and not use that product again...
