Overview:

ACCEL HP Spark Plugs are made with a Copper core which is a better conductor than Platinum and Iridium. They deliver a stronger spark especially in high performance applications where high combustion pressures are present. Copper is much better at dissipating heat than other materials which lessens the chance of a misfire. ACCEL HP Spark Plugs are gapable allowing you to open the gap exposing a larger flame kernel or close it if needed for high boost applications. All ACCEL HP Spark Plugs have machine rolled threads allowing for a more precise thread engagement and torque retention.

Features:

  • The Copper core is a better conductor than Iridium or Platinum plugs
  • Copper dissipates heat much better than other materials
  • "C" - Cut Design un-shrouds the spark kernel for a better burn
  • Unlike Iridium or Platinum plugs, the ACCEL HP plugs are gapable
  • Machine rolled threads for precise thread engagement
  • One step colder than stock
  • Whether using on the street or on the strip, ACCEL HP Copper Core spark plugs deliver!

Might buy a couple more.
Color: Demin Blue, Size: Large
In the process of losing weight and needed a nice looking shirt for work without spending a lot of money on something that will only fit for a few months. This did the trick! Fits well, looks nice, and at a great price.

The fit is pretty good, it's acceptable.
Color: Navy Blue, Size: X-Large
Very good fit. The sleeves are long enough, I guess. I'll be rolling them up anyway. I would like it to be a tad bit longer though for tucking in. Other than that it feels nice and lightweight, can't wait to wash it so I can use it for going out.
