performance plugs

I woulnt put denso near it lad ngk are the best plug you will buy. Seen too many denso's fail. You prob don't even need to change them unless they have huge miles on them, a good clean up usually does the job fine.

NGK are the most reliable plug I've ever used in any car, and also probably the best value for money. I've had a couple of denso's fail and Bosch plugs ran too hot and ruined my poor pistons

only possible way a plug can fail is from not changing em wen there due dumpming the fuel in and fowling em its all periodic maintance dudes
