spark plug choice for Peugeot 205 GTI track/sprint car
Posted: June 26th, 2008, 12:39 pm
This is one of the final areas I want to ensure is optimised for my purpose. The last thing I want is a spark plug to let the side down.
Currently I have BCP8ES (one grade cooler than the standard BCP7ES). But the car hasnt been driven in anger since they were fitted
I know competition 205s (like AB motorsport's) use more race oriented plugs.
So I have been offered these alternatives from an internet spark plug retailer, and just want to hear from other people with knowledge in this area. I have been doing some research myself into the design of the tip etc.
The short list I have been given is:
NGK
R7435-*
R7436-*
where '*' is the heat range (i.e. R7435-8, 9 or 10)
Denso
IK01-*
IK02-*
(* = 24, 27 or 31)
These are what the plugs look like in comparison:
BCP7ES:
R7435-8:
R7436-8 (with the shortened tip):
To recap on my engine, the power is up ~50% over standard, compression 2.5 points higher and revs up 1500 or so
