Spark Plug Upgrade
cjbiggs 2 years ago
So far so good. Swapped out the stock sparkies for one step colder plugs.

Worth it!

I started using these plugs on the orders of my mechanic haha. My car idles better and runs smoother since installing these and I currently run a VF39 w/pink injectors and 255 fuel pump on an 04 WRX.

    If I currently have no other performance mods except for a cat back exhaust but plan on engine upgrades in the near future could I go ahead and swap these spark plugs as my stock ones need to be replaced soon anyways? Thanks.

    • A: The general rule of thumb with spark plugs is for every +100HP over stock, you will want 1 Step Colder spark plug. So if you setup is not making 100hp over stock, you would not benefit from running 1 step colder spark plug and can risk spark/detonation issues

    Would you recommend these plugs over the stock ones, if all I have is a Cobb catback as far as performance upgrade?

    • A: The general rule of thumb with spark plugs is for every +100HP over stock, you will want 1 Step Colder spark plug. So if your car was making around 350WHP, then 1 Step colder plugs would be wanted.

  • Q: Spark plug Gap  Kevin 1 year ago


    Do these plugs come prepared gapped or will I need to adjust them myself?

    • A: These plugs are pre-gapped, and we recommend double checking the gap before installation.
