Product Information

Product Details
Part No. 8199
Warranty Details (90 DAY REPLACEMENT IF DEFECTIVE)
ACCEL's patented race proven spark plugs in a shorty configuration. The overall length has been reduced 3/16 in to 3/8 in (depending on the specific spark plug) to gain critical air gap between the spark plug boot and the exhaust manifold or header tube. This helps eliminate burning the spark plug boot or dimpling the header tube. The shorter spark plug length also can make it easier to install and remove the spark plugs in certain applications where there is not a lot of room to fit a socket or move a wrench around.

Product Features:
  • Shorty spark plugs for tubular exhaust headers
  • Eliminates dimpling headers for added clearance
  • Improves spark plug access to fit socket or wrench
  • Shorter overall plug length vs. OE style plug
  • Copper core center electrode
  • Projected tip
  • Helps eliminate urned spark plug boots
  • Shorty Header Spark Plug
