  1. Change Your Plugs!

    Posted by Josh C on Oct 3rd 2017

    After a tune, I could defiantly notice my plugs were junk, and I was hearing/feeling a cut out at WOT. After talking to Torrie I picked up 6 of these and problems solved!

  2. Awesome plugs

    Posted by Steven on Aug 9th 2017

    They provided consistant quality cylinder ignition over the entire RPM range.

  3. Superb

    You can buy a material part anywhere. However, buying from Torrie assures that the service with your purchase will be extraordinary!

  6. NGK one step colder spark plugs

    WOW, just installed these and what a complete change. The idle is smoother, runs and drives smooth. I noticed it right after starting that the idle was better and no jumpy cursing rpm. I also have Unleashed 93 octane tune and these definitely make a difference. Thanks Torrie and everyone at unleaded.

  7. Very fast shipping! awsome customer service!

    I ordered these online and saw they were at a gap of .0028 and thought that is what was recommended. I looked around online and AFTER the order, I noticed the gap most used .0030 and I reached out to Torrie and he was very accommodating and helped me out.
