Tune up

I have to give my 2010 jk islander a tune up. I want to use good parts but not break the bank, also an idea of what to get. Any ideas?

On older vehicles, when you gave it a tune-up, you had to change the spark plugs, distributor cap and rotor, adjust the carburetor, set the timing, etc. On our modern engines, you have fuel injection and the computer takes care of most other adjustments. All you really need to do as far as the engine is change the spark plugs. Your 2010 Jeep uses Champion RE14PLP5 (7440) Double Platinum Spark Plugs (stock from the factory) and NAPA sells that spark plug for $4.49 each. I would probably also change the air filter, and the PCV valve ($9.90 at NAPA) and maybe the oil unless you take care of that on a regular schedule. If it is really running rough, you could have a bad spark plug wire. But, if it is not running really rough right now, then the spark plug wires are fine so I would leave those alone. No need to change the ignition coils either. You may want to inspect the belts for cracks as part of regular maintenance. Have you changed the differential fluids per the schedule in the owners manual? If not, then I would change that too just as part of regular vehicle maintenance. Can't really think of anything else.

Hey thanks man, yea it's been running pretty rough. I have a k&n filter and cold air intake so I have to clean that. I want to do the wires and the plugs definitely! Oilchange is a must and when I changed my clutch I put in royal purple for the dif fluids

Look on-line at NAPA or on Amazon to price parts. It will give you an idea what parts may cost. Spark plugs wires are not too expensive.
