Just installed the stage 1 sri today. Went smoothly and WOW! Started the car for the first time and could really hear all the air being sucked in by the intake. Took it for a quick spin and now you can audibly hear the turbo spool and stock bpv. Highly recommend this intake to anyone.

This was my first modification to my 2012 Speed3. I had so little mechanical experience I had to buy the hand tools to put this on, and apart from some tight space taking off the stock intake, installation was pretty straightforward.
Personally, I think this is worth the price for the sound alone. Hearing the car hiss and breathe when the turbo spools up is awesome. It's loud enough to hear with windows up on the freeway above 0 psi boost, but not so loud that it'll piss off your neighbors. I've seen no change in mileage in the 2 months I've had it installed.
My butt dyno can't feel the claimed 12 hp / 17 lb-ft torque gain. I can feel less pull between 2500-3000 rpm while boost builds more slowly, which is a little disappointing. However, I compared telemetry data from track days at Willow Springs from stock to after I installed the SRI, and the acceleration is slightly better, getting me to 120 mph vs 117 mph on the back straight. Not huge differences, but that could align with 12hp. I could share the graph, but this won't let me post pictures.
Stop procrastinating by reading reviews, just suck it up and buy it. The only thing you might regret is not shelling out for stage II.

This was my first upgrade to a 2010 Mazdaspeed3. I purchased the intake in 2014. After almost 3 years, this intake still functions perfectly and continues to help make the car a joy to drive. No CELs, no problems whatsoever. The part itself still looks as good as it did when I removed it from the box.
Install took about 30-45 minutes and the instructions were clear and concise. All of the parts fit perfectly. The most noticeable difference is the sound - spirited driving reveals a very audible hissing noise as air enters the intake. The high-pitched whine of the turbo is also more noticeable than before. Highly recommended.

Love this product. the "whoosh" noise is addicting. they didn't have the color I wanted but they included some hp adding stickers and a nice letter. butt dyno noticed a slight power diff.

Recently installed this piece on my GenJuan, loving it so far! Improved the sound over the Mazdaspeed/AEM CAI that had been pre-installed when I purchased the car.
Only thing to note is that if you, like me, do not have the factory airbox elbow, you will need to find an adapter for the breather hose, as the CS SRI relies on you being able to remove and transfer this small piece from the factory setup. I worked around it by altogether replacing the factory plastic breather tube with some flexible heater hose and a couple of generic fittings (3/4" to 5/8") from the parts store.

Bought the stage 1 intake. So far it's been great, car no longer falls flat at 5.8k and let's you easily hear the bpv. Awesome product will definitely be buying more from corksport. My only regret is I didn't go for the stage 2.
