Your cart is empty.The RD series is a cold air intake system for the enthusiast craving mid-range power. Most intake tubes are strategically placed behind the front bumper to acquire colder, denser air. Although most of the RD series is a one-piece design, several are two-piece designs due to the mass air flow meters. Nearly all RD intake system is certified or pending by the California Air Resource Board and backed by Injen Technology’s limited lifetime warranty.

Expensive, but worth it. Dyno graph in the box shows +11hp, and man it really feels like it. It is a pain in the ass to install, because you have to install it by taking off the front bumper. People say you can sneak it in through the wheel well, but trust me, you can’t. Took me 3 hours to do it in a parking lot with not the right tools. But looks great and sounds great! Recommend the hydro shield because it does go down next to the fender

Purchased this for my 2004 Honda accord v6 3.0 and it is a big hassle to get the stock air box off but when you put of the cold air intake but it sounds great. you get a better response to your throttle and it has a mean rumble to it. kinda sounds like a v8 in a way.would highly recommend this product for your car

I own a 2007 Honda Accord V6 and after hearing great things about this Intake system, I decided to buy it since it was relatively inexpensive! I love the way this Intake sounds. When you're driving normal it has a nice whistle to it, but as you get deeper into the throttle, it sounds more and more aggressive, especially when VTEC is engaged. Full throttle gives the car a similar but louder sound of a European V8! I have noticed that the car has a better throttle response and is definitely quicker in the lower to midrange RPMs. Full throttle is improved also but it's not really noticed until it's in the power band. My only complaint with the Intake is the decrease in gas mileage, I'm not sure if it is from me wanting to hear the Intake at some point when I drive but there is a decrease. Other than that, great job to Injen Technology. I definitely recommend this product to anyone with an import car.

Blown away!! This thing sucks!! In all seriousness, it really is awesome. My TL is alot more peppy now and has a mean sounding whistle that's not too loud, but definitely audible. The gulp of air when you blip the throttle is mean sounding as well. I lost a good bit I'm weight from the stock airbox which helped too. Came with all necessary hardware and clear instructions. Very happy with my purchase.

I installed today and really wasn’t impressed at all . For the price it should perform better and sound better and the filter looks like it’s from the dollar store!

Great addition to my 2004 Honda Accord V6 6-speed. It wasn't a difficult install, but it did take a long time. I am very pleased with the performance of the intake. It whistles on acceleration, and roars after about 3000 rpm. I haven't checked the mpg to see if it has improved, but it is definitely a more efficient system than stock. Here is a video of my installation: [...]Here is a video of the sound: [...]

Great sound, exactly what I was wanting out of it. Mpg was slightly improved for work commute but on a long trip even better. Install is somewhat easy if you are mechanically inclined, if not YouTube and brace yourself.

The intake it's self is well made and works like it's supossed to, it gave me an increase in gas mileage. The reasons I give it 3 stars is because this particular intake System does not fit the 07-08 TL Type s 3.5 very well. There are fitment issues with the bumper, the cone makes it kinda hard to put the bumper back on because it rubs on the fog light this could risk a tear in your filter.
