Got it @ pro civic. So easy to install. I didn't notice any increase in power
However the power is noticeably smoother. For $90 and 10 minutes its so worth it.
Yeah P2R spacers are a no brainer, extremely popular product. We actually had P2R make this model back a year or two back, tested it on the 08+ Accord i4, 09+ TSX, and then brought in a customer to test and confirm fitment on the 2012+ Si
so anyone else ever had these on their honda motors? i dont know too many of my honda friends that would sport these... im just wondering if it really makes a difference or its just bull
I did a lot of reading myself on TBS. There are mixed reviews about them all over the net, but Honda owners seem to swear by them. Installed one on my Si. Have a few hundred miles on it now. Did I notice a difference with performance and sound? Honestly, its hard to say. The sound is a little different. A little deeper, no whistle sound like some TBS say. How about performance? Maybe some increased throttle response, but if I have to say "maybe," then obviously its not super noticeable. But if tests show HP gains up to 4, then the money is worth it. Hope this helps. Remember, I have an Si, not an EX. There are other posts on this topic in the 9th gen civic website
