lnf back fire
#26
yea its gotta be the plugs fix em before you need new ones or one melts into the block. my lnf ate up brand new NGK 1 step colders that way. Rapid Backfires in the 5500-6000 RPM range, i never felt power loss but it just knew it wasnt right. Kept me from NLS a bit till i got a Subaru exhaust note cause one was melted in the motor almost.
