aFe Power Silver Bullet Throttle Body Spacer Kit Honda Civic Si 12-15 L4-2.4L #46-37001

like the ease of installation, has a great sound, will know more about performance once computer adjusts so far so good. quality fit and finish all very good, installed on a 2014 honda accord sport.Update, been driving with the TBS and I have to say I was skeptical at first as I’ve run these on my truck with not much change. however Honda Accord with Direct port injection I noticed an immediate difference definitely feel the difference after the computer adjusted. More power on the high end more torq on the low end gas mileage has improved overall. Very happy with purchase

It’s awesome product! I have AEM cold intake and I didn’t have to cut any part of intake! Relatively easy installation. Only thing I have to do was and needed was longer throttle body coolant hose! I have 2013 TSX wagon! Sounds great with cold intake! V tech kicks in and shift change, it makes blow off like sounds! Power wise, low end about same but more power on mid and high! And Carb exempt in CA and shipped to CA

This fits a 2016 and up Acura ILX. It doesn't say it but it does. Took about an hour and like everyone else says, feels a little lost of power but should feel better after a couple days. Cool blowoff valve sound. Got it a day fast deliveryUpdate: my car feels great! Very responsive and pulls harder. It also smoothed ou the midrange power on half throttle. Mpg went from . 32 to about. 29mpg I'll take the trade off. My has injen cai intake rv6 downpipe and ktuner

Not a MAJOR difference except for maybe a slight increase in throttle response.Does make a high pitch whistling sound at cruising speed and a fun little whiiip sound when ya give it a pedal flutter.Install was relatively easy, the only hiccup was with my AEM cold air intake. Had to loosen the mounting bracket to give some clearance in order to get it to fit.

The installation of the spacer was quite easy, but adding a cold air intake pushez out the bracket to hold it I n place. As you can see by the pictures I had to make some adjustments with washers and still not what I want but it works for now!

i love telling dummy’s it’s turbo’d HA! gives it a lil whistle on throttle. love it

I am very pleased with the purchase of this TBS. I bought it originally for the "additional power", but was pleasantly surprised at the gained MPG when i keep my foot out of it. I did install this along with the Takeda Air Intake System at the same time, so gained power /MPG maybe different with just the Spacer. Installation was very simple, as long as you have a Tq. wrench (89 lbs) handy.

Quick install and looks very nice. Can't say I'm getting better gas mileage as I'm gunning it more often, but I do see a difference at the low end. My car does have more torque and it has seemed to have corrected what was once pulling to the right to now almost center with a slight pull to the left when launching.

Easy installation, ive Buy it with the Takeda SRICool sound low RPM (whissle)Not sure about any gain tho
