Description

Whether you’re passing some slowpoke or rocketing off the line, your engine will tear up the pavement with the RD Series Cold Air Intake by Injen. This high-performance piece of pipe optimizes your throttle response, boosts your engine’s power output and even dresses up your engine compartment.

The key to the RD Series Cold Air Intake’s success can be summed up in one word: location. Injen designed your cold air intake to ride right behind your front bumper—prime real estate for gathering fresher, colder, denser air.

Plus, your RD Series Cold Air Intake is an engineering marvel. Everything from the mandrel bent T-6061 aluminum tubing to the TIG welded brackets has been rigorously tested and tuned on Injen’s in-house Dynojet for maximum, reliable horsepower.

Your RD Series Cold Air Intake comes with Injen’s signature urethane air filter and stainless steel clamps. Tube and air filter covered by a Lifetime Warranty.

Notes

  • For most vehicles, the RD Series Cold Air Intake comes in your choice of polished or black finishes. Select autos, though, come in one finish option.

"I'd have to say the sound from the Injen intake sounds amazing. The loud deep roar of the CAI as you get onto roads and after stop lights just sounds great. Also the jump from the horse power and torque are very noticable as well. all around great product."

"This product is made from quality material and was made to fit my car. the only problem i had was the screw holes on the "composite fin adapter" had melted plastic in them from the production process. this is in no way autoanythings fault but was in fact an inconvenience. i had to carefully peel away the excess plastic that was inside my screw holes without damaging the seal on the adapter. after i finally did get it in, i can definitely feel a gain in mid-range power. i did not however, get the loud sound that i expected."

"My first car mod. Did alot of research on AEM and Injen products for my Prelude. The Injen seemed like the smart choice being $40 less than than the V2 and producing pretty much the same horsepower. Went in fairly easy, but then again I'm not a car whiz. Front bumper did have to come off. Overall, fantastic growl above 3 grand. PLus it sounds like i have a blow off valve after i shift. Looks slick once installed. Not a huge boost in performance or mpg, but it's there.....only had it for a week though. Instructions that come with it are also fairly easy to follow. Overall i give it a 9 1/2 out of 10. Newbie's to this stuff can expect a 3 to 4 hour installation period."

As soon as I started driving I noticed a jump in throttle response and also at high acceleration it has a nice sound that wasn't expected but its nothin like an exhaust of course. I am very pleased with this intake for my car."

Injen RD-1222 Intake Review

11 of 11 people found the following review helpful.

"The intake provided was truly a valuable purchase. Although I was not notified that it was on back order, after it arrived I was pleased with the product. The directions, although black and white, are available in color from Injen's website and provide a fairly detailed guide for installing the intake. It might take a moment to locate the spot in the picture, as they are very tightly-angled shots, but it's a very simple install anyway. Definitely a good investment, especially when coupled with a hydro-shield filter. Engine sounds great and I can feel the extra power."

"Easy installation, you do need to have a moderate level of mechanical aptitude to do the modification. The instructions are a bit vague because they are in black and white, so do a search for your particular vehicle and see if there aren't more color photos and opinions to do a double check. The power increase is not an exageration! You will be glad you did this!"

"Judging my mechanical skills between 1-10, I'm probably just a 6. It took me about 1.5 hours to install. I had to remove the front bumper which ate much of my time. I had to print out the instructions from INJEN's website for a clearer copy. The instructions were straightforward for the most part. It's knowing which part is which that can stomp you if you're not mechanically inclined. Use a colored printer, it's a big help! Once my CAI (cold air intake) was installed, I took my car for a spin on the expressways and boy was I grinning! You can feel the gain in horsepower PLUS the ROAR the engine generates when I shift from 2nd to 3rd to 4rth and 5th gear. The engine runs real smooth from all the fresh cold air it feeds on. I still have a stock muffler so I can just imagine if I replace it with a high performance. Now I'm waiting for the hydro-guard I ordered from INJEN to protect the filter. I definitely recommend my CAI!"

"This intake adds a great sound to an 04 Mazda 6S V6. Makes a deep growling sound that is suprisingly loud when accelerating. Also the perfomance aspect added a great low end torque boost and a little added launch into 3rd and 4th. Would definently recommend this intake."
