    pulled them all back out, coated threads with anti-seize, checked gap .028", put dielectric grease on tops, re-seated plugs, re-seated coil packs, cleared codes. Runs fine now. Weird that it didn't fire right the first time.

    are you running a tune?

    it might be this thread or possibly another where it was discovered that the gap agreed upon .025 versus .028 due to the amount of forced air with the higher tune.

    negative, running stock tune. Not sure how much boost that is though but it shouldn't be getting spark blow out.

    Folks,

    I'm using this guide to do a coil pack swap. It was all good until I tried to get the driver side 10mm nut on the bottom of the airbox. Any tricks on how to get to it? Short of pulling the engine.

    As I recall there is a useful diagram of that screws location in the Bentley manual. That's all I remember other than it being a PITA.

    10mm stubby open end wrench does the trick.

    What is the correct spark plug gap? Im about to replace my plugs and coil packs and want to make sure my plug gap is squared away. Also what are the best coil packs to get along with price? Thanks!

    Never saw this, sorry. I think my point was that when you sticky a thread its fine, but in general should be temporary. The DIY thread has to be manually updated now with thread links. Putting them all in a sub forum would make them easily searchable and keep the repository updated organically. Meh, to each their own. Just trying to help.

    I did my spark plugs this weekend with help from this DIY as well. Here is a list of my images, in order of work performed.

    Hi all. I am just about to do this as mine have 30k on them and now ive just given it a tune. I will install new factory ngk prf7q and regapped them to 0.026".
    my concern is the wide use of lube or coppercoat on the spark plug threads, this is generally a no no as it actually increases the torque you apply and the plugs come "precoated" from the factory.. see link below as I hope it helps any others with questions.

    Nene, why does your engine look brand new!!

    Question on the wire mesh cones.

    I reversed mine last week to make it easier to remove the cool air intake tuning. Any issue with that "mod".

    After doing it "factory way" many times I just thought in made no sense.
