how good are the denso plugs PART NO. PK20PR-P8, and will they fit my 96 import????

 

I wouldn't even put Densos in my lawnmower, let alone a car

I had one which cracked the ceramic tip and was about to break up.

I think "Harvey" had an engine faliure a couple of years ago related to a Denso / HKS rebranded plug breaking up.

Stick to a NGK PFR6B (for standard) or 7B (for mildly tuned)

 

hi andy
had denso's in mine but when i took it for a re/map to BOB RAWLE
he advised me to put n g k 's in he said the tips can go on them

 

i have just put some NGK PFR6B in my car, but i am pushing 308 bhp at the mo are they still good for that much bhp? or should i go for the 7's
