    MAINT When to Change Spark Plugs

    I was thinking of the things I can check on the car and wonder when (mileage) would be a good time to change out the spark plugs.
    I also want to know if this would cause my 1/4 times to be lower than stock.

    I searched the maintenance schedules and I didnt find it there.

    Anyone with a recommended plug manufacture/pn?

    here is the link with the different ones offered.

    As far as I know, our plugs don't need to be changed until 80K-100K.. You can change them earlier to get a little boost in performance (may not be noticeable) if you'd like..

    I personally use NGK Coppers and change them at around 10K miles.

    Not really with the plug changes, but I did notice smoother acceleration with the HKS DLI II.

    can't confirm their bold statement on hp and torque but looks like you're in the clear to buy these.

    copper plugs have a stronger burn. Down side is normally wears down near 30k.

    We have plats or double plats, I don't know yet as I didn't pull them off yet. Recommend at 105k, I'll be doing mine at 70k. You do not want to have a seized spark plug, hence why I'm doing them early.

    Hopefully I can do them without removing the plenum

    The guys at Uprev recommend changing them every 20-25K unless you've been tuned, I guess they've seen a 3whp gain just from swapping in new plugs... Very cheap HP :)
