We all know spark plugs are important to burning off fuel. But which is better?
Has any one used the new 4 prong platinum from Bosch.
Is NGK still the best?
Which plug is the best for high preformance and high RPM levels?
What Plugs are you using?

 

well your limited to NGK, and autolite. Maybe HKS makes some for our cars too. Rotoary plugs don't ahve elctrodes at the bottom like regular auto plugs. So those bosch plat +4 won't work.

 

shows how much you know

B#EGV plugs have electrodes on the bottom as per normal spark plug and LOTS of guys are running them in their rotary's.................

I will forever use the standard (for performance setups) BUR9EQ resistor plug combination.

Does anybody here use the torquemaster plugs??

 

I suggest visiting my site in regards to spark plugs other than NGK BUR9EQPs. I have tried the torquemaster plugs...

 

Be careful using non-resistor plugs!!!!!!
