    NGK TR55 plugs are popular choices in our crowd. Come pre-gapped, you should consider changing out the wires while you are in there. Get some MSD's for around $60 or so, all good maintenance at this point. As far as the O2 sensors, I forget what kind I installed with mine. I didn't order anything special, whatever came recommended from TSP

    You dont need the bosch sensors, they recomend them because the wire length is longer and you wouldnt need extensions. I would suggest just picking up some 24" extensions and you should be good to go. The wiring that comes in the kit will require you too splice the wires, Some people say it works and some dont, i dont think it does bc you really wont get a good connection. As far as plugs, if your running spray you will want a cooler plug, ngk 555 are popular, if not that just any type of plug should work.

    are you getting longtubes? and are you going with an ORY pipe or are you going to have cats?? If you go with ORY then you will end up having to go with a rear 02 delete OR buy a set of o2 sims. Personally I think its worth it to spend the extra 100 on sims and go with the ORY pipe. The ORY is normally 100 bucks cheaper than the catted pipe so you can purchase the sims with the saved cash and you will gain a few more ponies

    While true, you want to make sure you check them.

    Plug wires....stock are more than likely fine. Spark has so little distance to travel that the stockers are fine unless you have a high powered application and are having spark blowout issues.
    Although new wires aren't too expensive.

    you could always ohm test the wires for inconsistancy too.. make sure they are all good

    The reason they suggested the 13111's are because of the longer wires like stated above and they're actually vette rears which are supposed to be better about not giving you the heater codes and switching codes.
