The thing with the ITB's are that there are definately draw backs to it. Also unless you have a pretty decent build already they aren't going to do that much for you, unless you just think they look pretty. Someone can correct me if I am wrong but I believe on a stock GSR Itb's with tuning will only yield about 10-15 hp. While that is a decent number for NA Honda unless you have already done a good header, cams, raise compression, etc., IMO it is not the best bang for the buck to do. For one thing the stock head is only going to efficiently flow so much air, unless you do FI, without head work to increase air flow you aren't going to see the results that most think. Also after talking to someone who had them on a type R, he said he constantly smelled like gas just from driving his car, they release gas fumes that enter into the vehicle. As long as you know what you are getting into when it comes to getting ITB's they are great and these look like they will be another great Omnipower product. I run Omnipower flat face race valves and Omnipower full coilovers and have been extremely pleased with the quality and performance of their parts, especially when you factor in the cost compared to something that would perform equal to them.
