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!

Size: 5, Color: French Sand
Love the shoes so pretty but, the strap hurts my little toe but today was first time wearing so I'm hoping I just got to wear them a few times and break them in.. A friend has a pair and she loves them. She said they are very comfortable.

Size: 9, Color: French Sand
Obsessed with these shoes! They are the perfect classic nude heel. I hate the thick heel on a lot of nude shoes and this one is so different in the best way. It looks like a stiletto from the side, but as we know you get much more support. I think you do get your value for the money you spent, these were expensive but they are long-term durable heels. They are comfortable and the sizing is accurate. I’m a 9 and they fit me perfectly.

Beautiful comfortable heel
Size: 7, Color: Amber Gold
Love these shoes! I wore to a wedding without breaking them in and my feet didn’t start to hurt until 9 hours into the event! I am usually between a 6 and 6.5 and got a 6.5 and they fit perfectly.
