      Great plugs but they take an odd sized socket

      Like everything I get from Lowbrow these were exactly what I was needing to replace on my Sportster. Super fast shipping, the only complaint I had was they do not take a 5/8 plug socket. They take an 11/16 which of course I only had a short, instead of a deep well like you need... Not the end of the world, just didn't know it before hand so the job took longer than anticipated. Once installed the bike fired up beautifully!

      Lowbrow parts

      Great stuff! Got the louvered air cleaner for my efi sporty and it’s great came with all nessicary hardware. Got the breather bolts too, super cool design. Also picked up new plugs and a plug wire kit for when I relocate my coil. All good stuff fast shipping.

      Spark plugs

      Great replacement for stock plugs and much cheaper than the stealership!
