i'm gonna get my nuts shaved off for this but i was wondering what the difference was between the gen 1, 2, and 3 injen intakes. just curious. everyone seems to think gen 3 lags/bogs the least. did anyone notice design and pipe change? they all look the same.

what i remember reading is that the diameter is what has changed. the first and sec. gen where really big and teh mafs would read alot of air and in turn run lean. and from that you get your bogging not sure but that is what i remeber. correct me if i am wrong

it was in this forum it was a write up by blue bomber i think. there is also an awsome right up on how to cure the lagging problem completly with you CIA and you stock air box. it looks a little sketchy and the margin for error is kinda big if you are not machanically incline but the solution is awsome i will try to find it and get back to you

I'm not sure what the difference between Gens is, but either way, they still haven't solved the bogging problem. In the Injen CAI, it's caused by two things: the lack of MAFS fins (the biggest problem), and the fact that the MAFS is placed directly next to a bend. The lack of fins gives the MAFS false readings, and the uneven airflow from being next to a bend throws the readings off even more.

Actually, it's the exact opposite. The MAFS reads less air than what is actually entering the engine, so it tells the ECU to provide less fuel to match the air.

Actually, it's not very hard at all to get the piece out and in usable form. The hard part is if you want it to look presentable. Then you need to sand and dremel the bumps off, make the tube smooth using epoxy and more sanding, and then wetsand and paint it a few times. The mod has been sucessful 100% of the time in curing bogging/CELs caused by the intake. Here's a link to it:
