i have a 1999 v6 and most likely my spark plugs now are shot. its just some maintnance i wanna get done new fuel filter, oil filter and some new plug wires. i was looking at these, http://www.americanmuscle.com/ngk-sparkplugs-3403.html or these, http://www.americanmuscle.com/ngk-sparkplugs-7164.html theres a decent money difference which isnt my concern just curious as why that is.

 

Holy **** all that. Walk into an autoparts store and just get them..your ***** stock..you don't need 70 dollar plugs...

I think for my TR6's I was only paying like..14 bucks or some ****...

 

Just run copper plugs in it, If you run bosch platinums you will watch your MPG's go down. Platinum plugs suck for our 6's.

 

I got the iridium plugs for my car, for about 40$ though, and i have a noticeable difference on startup and a tiniest bit more giddyup.

 

How old were your plugs though? When I changed mine last a few were shot, and I found out they weren't gapped right. Changing that and the wires I could notice a small difference in performance and my mileage went up a bit too.

 

They were at about 55k. Nothin was wrong with em, just wanted something to do.
