Im getting ready to do a tune up and want to get the best stuff. I was thinking Bosh 4 Platinum for plugs (Anyone know if there is a gap?), a K&N Air Filter, but i was wondering what are prob the best plug wires to go with, and is there any difference in distributor caps, and finally the best fuel filter to use. Thanks in advance, oh and for those of you who looked at my pics before, I just got the PS2 hooked up, ill get some more pics up shortly

 

bosch +4 come with a factory set gap,, im currently using them,, i just ordered denso iridium plugs to replace my bosch with
i use NGK wires
stock fuel filter

 

i hear the bosch platinums aren't really that good. i would go with the densos too. and NGK plugs will do a fine job

 

NGK is good or get some OBX 10.3mm

 

OEM = NGK, I'd stick with them. Gap should be in the manual.

As for aftermarket wires, you will not notice a difference between them, they are all about the same. If you want blue or yellow this is an awesome deal. I got mine back when they still had red. Nobody makes an aftermarket distributor cap for the 2.3, so you're stuck with stock, which is perfectly fine.
