choose: umnitza/simota or racing beat? i know intakes for our car dont do much in terms of "noticeable" power or gain, i know the racing beat gives a lil gain, nothing significant. ive read bout the umnitza and most ppl have just said it sounds great, they havent said much bout power gains or mileage gains, so i was just curious which one to get? (i have the greddy sp2 installed so far, so i also wonder which would be a better sound combo?)

 

I know perhaps you may think you are the only rx8 owner to have this question, but you are not.

Search.

 

umnitza claims 8whp is added. There are some that add 2-4 more but you should probably choose your intake by sound.

Here is a nice video of it (not my car)

 

go with AEM!

 

This is my install video Quicktime 7 required.

Judge for yourself. HP gains on mine, doubtful. Research it.

this is the most in depth thread for the umnitza intake.... it will answer all your questions... mainly the last few pages.
