im looking to buy new intercooler couplers because the stock ones dont fit the injen IC pipes very well. the injen pipes are a little too big and i can barely get the stock couplers on. i'd hate for one of the ic pipes to pop off. i was wondering if anybody knew the size of the stock couplers. i was thinking about buying a pair of black 45 degree 4 ply silicone couplers off of ebay or something.

 

Measure the OD of the Injen pipe and buy a coupler with an ID of that measurement.

 

The stock couplers will fit. Here is a tip:

Spray the ends of the pipes with hairspray and it will help them slide on. The hairspray will dry and be tacky after that. Switch to T-bolt clamps if you can as the stock worm clamps arent that great.

 

You are better off with silicone couplers.

They will be 2.5" if you plan on switching, but why spent the extra money. But I would advise the t-bolt clamps. I bought 2, 4ply 45 degree silicone couplers from ETS and paid $65 shipped plus an extra $20 for t-bolts.
