Asking is the first step to learning, no need to be shy here. You’ll probably get a wide array of answers to these questions since everyone has their preferences. Just keep that in mind. You’ll most likely have to formulate your own opinion based on the information you receive and what your personal budget can afford.
Here’s what I run in my 79’ CJ….. (Not all motors respond alike)
Spark Plugs & Wires: Splitfire http://www.sparkplugs.com/splitfire/Understand they are the original high performance plug. I run a converted fuel injected AMC 360.
The duel mag wire sets have two premium magnetic suppression core conductors, with only 250 ohms of resistance per foot. The triple platinum plugs are exceptional for fuel injected engines as well as for turbo and nitrous. No, I have NO plans to run a nitrous system.
Synthetic Motor Oil: Valvoline SYNPower http://www.valvoline.com/synpower/index.aspI don’t care what anyone else tells you about conventional versus synthetic, but synthetic is the way to go…PERIOD…!!! There are two things that KILL an engine. One is dirt, and the other is HEAT. Synthetic motor oil solves both problems far better than any conventional motor oil EVER will.
Valvoline SYNPower has as most synthetic oils do, special chemistry with more durable anti-wear additives that stay in the oil longer. What you get is this; ultimate protection against the three major causes of engine wear. HEAT, DEPOSITS, and WEAR. With a balanced combination of full synthetic base oil and premium additives, SynPower helps prevent engine stress from reducing engine efficiency, fuel economy and performance. SynPower is for anyone who wants to protect their engine and keep it running properly.
My older CJ and Dodge Cummins where converted gradually to synthetic oil as to NOT create any instant leaks that have been known to happen when switching. I gradually worked my way to full synthetic oil over four changes and am glad I did. Synthetic will require less changes versus conventional too.
Air Filter: K&N http://www.knfilters.comSimply put, a K&N will be the LAST filter you EVER buy. Simply clean and lubricate it periodically and it will outlast the vehicle. They are designed to increase horsepower and acceleration while providing excellent filtration.
Good Luck…
