Just a bit of background, I have a CP-E CAI and recently purchased the Mazdaspeed3-specific HKS SSQV (part # 71004-AZ008), which has an angled flange to help clear the TMIC shroud. I attempted to install it in recirc, but I couldn't get the stock recirc hose to fit without kinking, so I purchased a new one from SU. The fitment was OK, but as the pictures below show, the recirc hose still had a kink and the shroud was touching the SSQV. I figured over time that the hose would apply pressure to the valve due to the kink, but with the shroud keeping it in place, something would have to give (bolts, gaskets, clamps) in time.
So after doing some research, some people use a copper pipe to alleviate the problem, so off to Home Despot I went. Instead of a straight pipe, I bought a 45 degree, 1" copper elbow and some 1 3/4" hose clamps for $10.
I hacked up the stock recirc hose because it has a natural bend on one end, and used the copper elbow to angle the hose towards the inlet. Works great, doesn't rub against the intake like before, and the SSQV isn't touching the TMIC shroud any longer. No more kinks either, even drives a bit better now.
