as far as oil personally i use Red line 10w30, its a synthetic oil and runs about 7 bucks a qt, according to redline the oil is good for like 12k miles personally i change it every 3 months but i only drive it 100 miles a week so im still under my 3k miles, i like k&n oil filters and as far as plugs ive heard alot of good things about ngk's and my buddy has i think its a zex kit and he uses their plugs he loves em. as far as someone askes about plug wires, i run 9 mm wires i look at it as the less resistance the charge has to fight the better, msd makes a good coil pack msd8241 they go for like 75 bucks each,
ive also read about nology hot wires they are supposed to be pretty good but i havent seen them in action yet. hope this helped you out,
also on oil Royal Purple makes a damn good oil too but again your looking at 7 bucks a qti think it was consumer reports that went through oils and they determined that after like 100k miles there was only like one millionth of a differance in wear between regular oils and synthetic, but i know mm&ff did a dyno test and gained 2hp and 6ftlbs of torque changing all the fluids (engine oil tranny and rearend along with a redline fuel injector cleaner) so its worth it to me
