    So I just recently purchased a stealth intake to toss onto my car and had everything bolted back onto my car but forgot to put on the water outlet...well as I was putting on it. The lower bolt hole got stripped out :/ anyone know if this is fixable?

    I drilled my out and tapped to the next size. Had to use a cap bolt because the hex head bolt would hit the casting.

    Google E-Z Lok as well. Same solid threaded insert as the ones Frank mentioned above, but, from my experience, an easier install. The locking prongs always seem to get in my way on the ones Frank showed...and the E-Z Lok's can be installed either with a screwdriver in the slot, or by just threading the bolt in the insert all the way, and using a wrench or socket to install the insert. Either of the inserts will work fine though.

    One thing you may want to look at though...how much room do you have to the edge of the intake? Any of these solid inserts, which are pretty much bulletproof, are nonetheless physically larger than a typical thread insert.

    A buddy ruined an intake trying to install one on a stripped out carb mounting hole...just something to keep in mind.

    Thats what im worried about as well. I had just sold my other intake to a guy who his water outlet stripped and his mess up on him too as well so im a bit nervous on doing it myself

    They act just like a bolt, first few threads are tapered, threads are very sharp to re-thread/repair damaged threads. They are called Taps or Chasers......

    There are 3 types of taps, tapered, plug and bottom, but because the threaded hole in the intake is quite shallow in depth, only the plug and bottoming tap will work. Taps or chasers can be used to repair the damaged threads, if only the first couple of threads are damaged, you should beable to chase/repair. If more threads are damaged/stripped, then you would have to drill out/helicoil insert repair.
    When using taps/chasers, have to be very careful that you do not cross thread what is there already. A good auto parts store should carry these for 5/16" x 18 good luck!

    when I put the bolt it, it feels like it goes the past first couple of threads then it starts to catch then lets go...I hope that make sense

    That usually means the threads below the first couple frozen to a bolt and sheared off.

    Chasers don't usually fix that mess. The insert shouldn't be too difficult. I always just put the bolt into the insert then ratchet them in. Never screwed one up yet doing it that way.

    Specifically if it's not a load bearing bolt, I just pick the insert that has an OD that matches the bolt I was putting in, get the new smaller bolt that fits in it, and a HD washer. I always find that easier than drilling and chamfering the old bolt hole. Just use like a cylinder hone before you screw in the insert. I like EZ-Loks a LOT.
