What is the best oil filter, spark plugs any wires for a 1997 Cherokee I been told different things.

Also what is the gap for a Cherokee 4.0

 

Filter: Not fram. Wix/Gold, Mopar etc...
Plugs: Champion Truck Plugs. Forget the P/N. They're cheap.
Wires:??

Gap is .035"

 

I think I bought the cheapest plugs last time and gap them to 40 or 45

 

This...

 

.035" is the correct plug gap.......after that, the other items are subjective.

 

For filter, it's a great idea to go with the oversized if you can. I'm not 100% positive if these will fit in a 97, maybe someone else will comment on this. If it's like a 99 then you should have lots of room.

Here are part numbers for *quality* oversized filters:

K&N Gold: HP-3001
Mobil 1: M1-301
Motorcraft: FL1A
Napa Gold: 1515
Purolator: L30001
WIX: 51515

Wires I would recommend Mopar or NGK. I have NGK RC-CRX026... they blue!

Plugs are Champion RC12ECC (labelled as "Year Round") gapped to .035"

 

Don't buy Fram!
Champion copper plugs
Quality wires (a lot of people like Napa's wires)

 

what are the cons to a Fram filter?
ive ran fram on all my vehicles for the last 7 years, never had a problem with any.

 

frams have a poorly designed anti drain valve and most, if not all, cherokee filters are mounted upside down, so overnight you run the risk of draining the oil out of the filter. also the newer frams are glued together and the glue breaksdown creating gaps that debre can flow through....overall just a poor design.

and to answer the OP question, i use a wix filter, mobil 1 or pennzoil 10 30 champion plugs gapped at manufacture specs and bosch plug wires

 

My old filter I took off was a wix but last night I put on a k&n oil filter and changed my plugs jeep starts right up now.

 

I have this set on my 99 and would i would use M1-301 (oversized) oil filter.
