what he said ^
just to make it easy tho stock replacement wires will be fine and the plugs will depend on what mods you want to do

Taken directly from Nick's thread:

"Brands that most tend to go with are either Copper Core Autolites or NGK Spark Plugs. Get these at your local auto parts store also. They range as follows in order from hottest to coldest plugs...remember...you want the hottest spark possible...so running a super cold plug on a larger pulley to combat knock isn't the best plan...ACD's, AL606's, and AL605's are basically for stock cars or very small bolt ons still running the stock S/C Pulley or modded N/A guys...you want to keep a hot spark. NGKTR55/AL104's for your 3.4" Setup, TR6's are a tad cooler...best used around the 3.25" pulley area, and AL103's...are for the extreme supercharged application...3.0" pulley or lower."

Until you modify, AL606's seem to be the consensus on what you want.

Also from Nick's thread:

"If you need some new wires, opt for the stock Lifetime Warranty Auto Parts store brand from your local auto parts store, but if you want to upgrade and need new wires now is a great time. Coil Packs, leave the stock ones...don't waste your money on MSD's as they are actually proven to fail within a years time and put out LESS spark than stock units. Companies that offer aftermarket plug wires are MSD Ignition, Taylor Wires, and PRJ Performance. All ranging from 8mm to 10.4mm monster wires. Cost: $60-$120"

That's what's up^ I run the lifetime warranty wires from AutoZone...
