Thread: Spark plug question

Just want to double check what people recommend running for Autech sr20de engine, higher compression - lower heat range?

BKR6EIX-11 this is what i believe i fitted last time i changed them.

After reading this though SR20 Forum - Spark Plug Gap - Need Final Word

Leads me to believe maybe i should run BKR7EIX-11.

for n/a high compression id say might as well go with a 7 heat range. Im sure the 6 will work just fine but might as well.
