A 1996 Jeep Cherokee.
IT appears to be the same filter as an STP S16 fitting many Chrysler/ Jeep applications.
Why can’t I find out what a STP S16 oil filter fits? Come on! It can’t be that hard to just say
Yes.
An S16 STP is a Chrysler filter. You should find this same filter for 90's Jeeps, Mini-vans, etc. Fram is PH16. Tech 2000 (Walmart) is ST16. Valuecraft (Autozone) is V16.
Lift the plastic cover off the top of the engine the Air filter lid is towards the back of the engine.loosen star bolts with an Allen key and lift lid towards you. The filter is inside. Replace and refit lid and plastic cover
S16
Go to a gunsmith
If by S16 you mean a Phase1 S16, then it is right above the throttle body, but on the other side of the bracket, right next to the cylinder head, with a plug on top of it. You can trace it from the TB as there is a hose running to it from the upper part of the TB housing.
It won't be back
