    Spark Plug Gapping

    I've got a 01 Firehawk which I've put NGK TR 55 plugs into. I gapped them at .054. Does anyone know if this gap would cause any issues? The car seems to run fine, but I just want to be sure that I shouldn't have left the plugs at the stock .060.

    The only mods I have are as follows:
    Blackwing Lid w/Holley Powershot
    SLP Dual Dual catback
    Smooth Bellows
    MSD Wires

    so...not much.

    .054 is fine. I've tried everywhere from .050-.059 and it drove fine everywhere.

    get it from underneath with a swivel extension... if you're not incredibly buff, your arm might just fit up between the cat and tranny. (i'm assuming you're talking about the number 8 plug which is the rear passenger side) I didn't have a way to lift the car so I got the passenger side up on a high curb, by backing up across a driveway. Whatever works! good luck!

    i had to buy a swivel extension. With that it wasn't all too hard. The hardest part for me was trying to pull the plug wire boot off the plug... My arm didn't really fit through there too well. The swivel extension was really the only way I would've been able to get to it myself. Dealership actually told me they would've had to pull the engine to get that plug... PSH!

    Not yet. I'm actually on the market for some LT's right now. Its kind of a bitch getting that #8 plug w/ stock manifolds though.

    On stock manifolds, I still couldn't get my #8 plug from up top even with coil packs completely out of the way. I don't remember if I tried again from the top once I got my swivel extension or not though.
