Ok. Have problems with the idle issue like everyone else. Convinced my wife that it was due to the intake having frozen and busted. So here are pics.









The pipe is a custom done job by a muffler shop. Pulled in and removed my intake. They fabbed it for me in about 30 min. Drilled the holes and treaded them for the brass fittings. cost--$43. The coupling boots are from auto parts store, 3" to 2 1/2", but had to mold the smaller side with a heat gun for it to fid onto the throttle body and the filter box. $15. Paint was $6 for the hi temp stuff. Had to replace couple of hoses for less than $3 from parts store.

So in all, I've got 'bout $60 in this mod.


Now to just get that dang idle fixed.

 

any particular reason the pipe has a smaller diameter than the throttle body?

 

The shop was gonna use 3" but with the brake cyclinder in the way, they went with 2 1/2. The original plan was to use a 1:1 coupling, but for that size, it would have been expensive. So they flared out the pipe to 3" on the ends so I could use those couplers.

 

all I can say is that since the pipe has a smaller diameter than the throttle body, it could be a restriction to air flow.
overall, I think it looks good, but it would be better if changes in cross section were non-existant.

If you look at that last pic, the pipe didn't have to come out as far as it did from the throttle body before making the turn to the AFM: it could've left the throttle body at an angle to mate with the AFM.

 

I can't really complain, the shop did the job in a timely manner, and I think it was their newest employee who did it.
