I would buy it again
I paired this with Steeda’s drop in filter. It actually does run better. Small investment and effort = small gains but I’m totally happy with it. I did do some deburring of some of the sharp edges and added some washers because it seemed like the longer screws were bottoming out before it was tightening up and I didn’t want to take a chance on damaging my intake.

Really Works
I have a 2011 GT automatic with Steeda cold air intake and a SCT cannned tune. I have used Steeda products for many years and have always had great success with them. I have read about these for many years but always thought of them as "snake oil". During a Steeda sale I decided to buy one based on other reviews and it really does work, crisper throttle response, less pedal pressure to make the car accelerate, it may not add horsepower but it does improve driving enjoyment. A worthwhile modification for the price.

2016 California Special
More than satisfied! I now get an immediate pull from stop, no hesitation, a major response as I gently pull away from that Maserati SUV, no doubt the Throttle Body Spacer delivered. And, when I dropped into Sport mode, I actually had to back it off! A completely different and powerful pull, like I'd put premium gas in. Install was clean, easy and everything went back together without a hitch. If anyone is thinking maybe, then you just need to take it from here, do it and get the GT you paid for, without a doubt!

Throttle body Spacer
Basic hand tools and it's about as simple as anything. fyi if you have a hard plastic intake tube like the AirRaid, it's a little tough to get the fitment right. Be extra careful with the air hose clips, as they are extremely weak and can break. All in all 4/5 stars because it doesnt come polished, but precision design and the unit went in in less than 20 mins. No whistle like other brands have reported. And no real gains I've noticed in the 10 mins of driving to autozone to replace the clips I broke =/ Looking forward to seeing if the mpg from my commute goes up!
