CAI stage 3; cont.
Now, to finish this SOB... you'll take the 1/4" fitting, slide it into the driver's side rubber line, and use the clamp to snap over one side of the fitting/rubber line. Now, unclip and pull the passenger line from the engine (it should already be unclipped from the TB), connect and clamp the TB side end of the line with the other side of the fitting. (now, you should have the driver-side line connected to the fitting and engine, and the fitting should connect to the passenger-side line that's not connected to the engine) Connect the passenger side line back onto the engine and clamp it.
Boy is correct on capping the TB inlet/outlet holes, but I used aluminum foil and sorta molded them as a cap so they wouldn't fall off. Put your airbox/intake back on and start up the car. Look for leaking antifreeze. ...it shouldn't be if you remembered to clamp all the ends. Go out and have fun. ps- I think Iggdawg on the other club said this mod gave him 3-4 hp and around 5 lbs/tq.
Overall, I've spent $1.19 +tax on this whole mod. This mod took me about 1 hr, because I was working on a hot engine and couldn't figure out how to get the passenger line to slide over the fitting. I found out an hour later...
*Although the rubber lines may be 5/16", a 1/4" inner diameter fitting shouldn't be a problem. If you were to get a 5/16" fitting normal flow, it'd be a little harder to slip the fitting into the rubber lines. AFIAK, the 1/4" fitting was difficult enough for me to slide into the rubber lines. If you can find a 5/16" fitting, buy it and try if it fits*
*Another note, all the ends of the rubber lines already have a metal clamp (you'll be working on only 3 of them) so you won't need to invest in extra clamps unless you're buying rubber caps for the TB*
CAI stage 4... This mod will work better when you have phenolic spacers installed. That way the engine heat will not heat up the intake manifold by metal to metal contact. This way, only underhood temps will affect the manifold. If I can get the chance to cut some out, I'll try to sell them like what Subachad is doing.
