What's the difference between the two? I know that the otrcai helps with heat soak and the maf sensor is relocated. But is there anything else that im missing?
The otr basically eliminiates heat soak. The amount of air get that gets pushed in is much greater and it doesn't have the biggest restricting factor, the 90 degree elbow. Otr's are made to function, and function well.

The vararam will make use of your scoops if you take the plugs out or modify the plugs by cutting squares in the front of each plug to help direct air down to the filter. You should also seal the vararam tray to bottom of your hood to keep the air traveling down toward the filter. Plenty of threads out there, with pictures, that explain this in detail. I upgraded from the K&N to the vararam, there is no comparison. A svede is a huge upgrade as well.
You're comparing the the worst cai to one of the best OTR's. Your car will be faster and less issues with KR with the Vararam.
I've had the Vararam and the SSOTR and I won't claim to know which one makes more power, but the fit and finish, overall look and maintainability of the ssotr is much better. Seemed like it would be a pain to get a replacement filter for the vararam.
