Gap spark plugs fired by Light Speed Engineering's PLASMA CDI systems to .032"-.045" for standard compression engines (7 - 8.5:1) and .026"-.034" for high compression engines (8.7 - 10:1). Turbo and Supercharged engines should run a spark plug gap of .026" - .034". Install the spark plugs and inserts using 15 and 25 lb/ft respectively, using anti-seize.
Light Speed Engineering's standard issue spark plugs are pictured to the left. Single ground electrode with a short body make these a durable option for most applications.
W24EMR-C: Used on low and standard compression engines. $2.95 each.
W27EMR-C: Used on standard and high compression engines. $2.95 each.
The standard reach (1/2") spark plug adaptor is also pictured here. This adaptor is used when converting aircraft engines using 1/2" reach aircraft spark plugs to 14mm plugs. Light Speed Engineering's spark plug adaptors are made of high strength aluminum bronze.
*These plugs and adaptors are included with ignition kit purchase for those with 1/2" reach.
Additional or replacement parts are priced as follows. $15.00 per adaptor with washer ($60 per 4-cyl set) $2.95 per sparkplug
