I got the SRI from corksport for my 09 mazda6 and i am in love, the throttle response is awesome. The power is upgraded, sound is much b6 etter and install was a breeze. Not to mention the shipping was fast! I couldnt believe how fast it got to my front door! Ill definantly buy front these guys again! I look forward to future parts for my 6 from Corksport!
