    Maybe I'm wrong, but I would think that a similar 1/4" setup might allow slightly greater flexibility and slightly more room than a 3/8" setup?

    Well, just finished replacing the plugs and it wasn't too bad. Had an issue with the coil pack bolts on the driver side for some reason, so I upgraded all of them to ones that aren't so soft. Less than 5 bucks for a pack of 7 bolts... I'll take it.

    Now to install the JB4... whoop.

    I had problems with the driver side bolts as well. I never was able to get the middle one back in - it just refused to bite. What did you replace them with?

    Picked up a (7) pack of M6x1.00 20mm bolts from AutoZone. The are slightly shorter than the OEM but they worked perfectly and like I said, <$5.

    Hey guys what did you torque the plugs to and did you adjust the gap of your new plugs? I heard new plugs should be gapped to 0.26 is this what you guys have done?

    0.022 as recommended for the JB4, torqued with my calibrated arm.

    Check your gaps, don't trust that they're gapped at whatever they claim.

    A gap anywhere between 0.022" and 0.028" is good. The stock 0.032" is just too wide.

    As for installing the plugs, these are the normal flat gasket seat (the gasket is on the plug when you pull it out of the box). When you install them you'll feel the gasket crush, then stop. Roughly 20 ftlbs.
    Taper seat plugs that don't use gaskets are a bit more choosy on install torque.

    Worked like a champ! I used class 10.9 yellow zinc coated (Fastenal part # 0128749) and it threaded in instantly.
