Accel U-Groove Spark Plugs For Harley Big Twin And Sportster

U-Groove performance spark plugs have a patented U-shape cut into the ground electrode that produces a double wide, hot spark to ignite standard or even high compression engines. The sintered alumina heavy-duty five rib insulator eliminates flashover and overheating that occurs with high performance and long range applications. Accel U-Groove spark plugs use the purest copper/nickel alloy electrode to produce a broad heat range that is highly foul-resistant and dissipates heat better than any other material. Racing and street performance has proven that U-Groove spark plugs deliver hot spark and high performance.

Features:

  • Accel's state-of-the-art, U-Groove spark plugs with ground electrodes, copper glass inner seal and electric heat seal prevent leakage in high-compression engines
  • Permit the spark to develop a larger, fuller flash for a more complete burn
  • Sold in pairs

They fit great.
If you have an Harley Iron, just keep in mind you'll need a 3/4" socket to install. The OEM ones are 5/8". They fit perfectly though and work very well. Mine needed some adjustment on the gap too, but with the 2 dollar gap tool Revzilla sells, it's a piece of cake. I had these installed in probably 10-15 minutes.

Not a good fit for 2002 XLH Sportster 883
Due to these spark plugs being 3/4 inch vice the OEM of 5/8 there is not enough room to install them. The block has a lip that hits your socket and doesn't allow for proper fit and install. Ended up breaking one trying to use a different socket.

2015 fat bob
except for the odd size (you'll need a 5/16 deep socket) it seems to perform well with the new coil & 8mm wires.

What a difference!
It couldn't hurt to change your plugs. They are pretty inexpensive. In my opinion a fresh plug always boost performance. In actuality it made a noticeable difference in acceleration.
