I have a ‘11 Mazda RX-8 GT. Looking into performance and sound upgrades :)Any help is appreciated!
Are you sure its a cold air intake? There is a short ram which the filter is in the hood so all the hot air gets sucked in. The long ram or sometimes refereed to as cold air intake goes under the car bumper which sucks cold air. Is can be possible if your filter is in the car hood.
Because you have a rotary mill I would encourage you to look on the Mazda website under the Rx8 section. Yours is a unique situation. Performance can be upped considerably, but the rotary engine is a different animal. Enjoy
First don't waste money on big name intakes like aem or kn. It's just a shiny metal or rubber tube with a filter that truly doesn't suck in cold air. You're stock airbox can draw as much as you're stock engine can take. Engineers designed it that way. Car manufacturers have strict economy, power, and emission requirements they must meet and if they could raise horsepower and emissions with a metal tube and filter they would have done it stock. However, look on eBay for a cheap intake if you must. Don't expect a world of difference but they can clean up an engine bay and sound good. Exhaust ehhh hard to say but please don't buy a fart can or 3 inch exhaust. It sounds terrible and ricers know nothing about performance.
something is wrong. Cold Air intakes are designed to increase horsepower due to an increase in fuel/air ratio. I'd recommend double checking to make sure if everything is right. It could be your MAF sensor or maybe throttle body.
