I can't speak for the Gen 3, but the R2C is a good intake. No matter what you read R2C is not a true cold air intake. R2C is more of a short ram intake, whereas the Gen 3 is a true cold air intake. You should get more gains from the Gen 3 over the R2C, but you have to shell out more money for the Gen 3 than the R2C, and it may only be a couple of hp difference, if any until you get a tune. With my R2C I noticed a loss at higher RPM, but noticed a little more from the lower and mid range torque.

I'll be selling my R2C in the next few weeks for a Takeda CAI if you are interested. I just have to get the Takeda powder coated before I install it then my R2C will be fore sale.

I'm not sure what the install process is since I haven't done it yet, but it does require you to take the front bumper. Although with the Gen 3 sometimes you have to cut the radiator shroud.

Stillen has slightly more gains. But maintenance is far more involved. The R2C filters are the best in the industry. The R2C will also be louder. Can't go wrong with either one. Just depends how willing you'd be to go through all the steps to clean the Stillen filters.

Very easy, undo the two straps (can't think of the correct name for them) and then slide them off.

After a lot of research I decided on the R2C. All the dyno sheets I've seen shows it makes more midrange power(usuable) and the Gen3 makes more at 7400 rpm which is right before redline.

So I couldn't justify the extra cost and time to maintain it for 3 more hp at redline.

How much more Horspepower and torque did you get after you installed the R2C filters?

Stillen Gen 3:
Pros
1. best hp/tq
2. cold air intake
Cons
1. installation
2. maintenance (filters hard to access for cleaning, but this is not something you change or clean that often)

R2C:
Pros
1. easy installation
2. easy maintenance
Cons
1. gets more heat
2. not as good as a cold air intake

I have the Takeda Cai and made 20wtq to the wheels in the midrange rpms 3-5k. Cai can gain a lot of torque in the mid rpms and on top, just need a proper tune to make the most power. As for ease of install, the front bumper does need to be removed to "properly" install the intake. I put the quotes around "properly" because someone always responds and says they installed it without the bumper removal, but in reality you can't get the mounts tight enough without doing so.

Hey '11G37S,

was the R2C bolt on and go or did you have to do any tuning or tricks to get the car to "learn" the new set up after putting them on?
