best spark plug

[krazykyle]

what is the best spark plug to run,what's a good bag for the buck.i have been looking at those E3 spark plugs but 6.99 a plug is alittle to much it seems.are the bosch platiums good or the good old ac delco ones fine.just thought i see what you guys are using.

I've used Bosch Platinum and AC Delco's with no problems. You really aren't getting anything more out of the E3 to justify the cost.

I use AC Delco R43LTS...they work better than the expensive plugs

Same here, standard A/C Delco plugs, R46SZ.

AC Delco or NGK.

i would agree with everyone else Ac Delco is the best for our car especially on a daily driver type car. But i would love to try te PULSTAR ones

I would have to agree that AC Delco are about the best, I also use champions from time to time. Heres a shocker though, all the turbo regals around here use autolite plugs. Yes, an autolite spark plug. Best plug for the turbo regals as per my best friend, his brother, his dad and his uncles all whom race turbo regals.

Autolite. Hands down.

 

[megaladon6]

it all depends on the car. german cars? bosch, hands down. ford? autolite. overall i prefer NGK. i ran delco's in the monte originally and it was not happy. i changed to NGKs and they've been great.
