Hey there! First recommendation is to ensure you're using the correct map. If the Redline Intake is your only power modification, you will need to use our "Stage1+Redline" OTS map. Beyond that, reach out to our Customer Service Team at 1-866-922-3059 or support@cobbtuning.com and we'll help get to the bottom of it!

it's the Boomba I hae seen so much lean and rich cause of the boomba bpv

Do you have any other modifications done to the car? The combo of this intake with our supporting +Redline OTS files should be pretty solid. It may be worth double-checking the rest of the system for minor air leaks.

@@cobbtuning I only have a catback, So I ended up changing my spark plugs and both o2 sensors and nothing still check engine light, so I re-installed my stock air box because my “dam” dropped to .688 and the car was stalling and driving really bad, since then the check engine light hasn’t came back and my “dam” went back to 1.000 I’m not sure but most people in the forums say OTS tunes are not reliable. So now I have 800$ intake I don’t use lol

@@domgerardo2096 vaccuum leak maybe?

@@LunasLostLoveturns out the MAF harness Cobb gives you with the intake is defective, found this out through Reddit never had any boost leaks or vacuum leaks.

@@domgerardo2096 glad I just saw this. I just installed this intake today so I’ll keep an eye out and see if the same thing happens to me. If you don’t hear from me then everything is working fine.

The intake and supporting calibrations are both covered under their respective CARB EO. You can find more info on the EO links on our product page. www.cobbtuning.com/products/air-induction/subaru-redline-carbon-fiber-intake-wrx-2015-2021

@@cobbtuning woah, awesome. Thank you for that!

That one has been out

Yeah I’m also wondering the same thing!

@@Silentdott No it's not available for the 2008 - 2014 STi

Keep your stock filter. Check out project farms video where he dumps sand into air filters to see how well they filter.

@@daviddin8863 another project farm watcher, you are a man of culture! I was literally about to go watch some of his videos once this one finishes! Cheers!

This is my issue because the big SF has the whole intake pipe replaced with a 3inch diameter pipe, the Redline just keeps the stock intake piping and replaces the elbow and box thats it? At least thats what it looks like...Im trying to figure out why they wouldn't have used the Big SF pipe, shortened it if necessary, made the Maf housing integrated into the intake pipe and then just had the carbon fiber box. The way it was designed doesn't make sense to me, and it makes me believe also youd get more out of a design with the SF pipe and the Redline box.

You don’t re use any stock piping for this intake. There is a 90 that attaches to the bottom of the intake that runs straight to the turbo. I had nothing but problems with the big sf with afr, and the motor would misfire and even stall sometimes. Re adjust filter to the 1” mark that Cobb stated in the instructions, and problems would come back after awhile. The tabs inside the maf housing on the redline eliminated those problems for me. Definitely more power all the way through the rev range with redline vs the big sf which felt less than stock until the rpm’s got higher. Only downside is that turbo noise isn’t as loud with the redline. Also it’s a different tune than the big sf

not really just looks good and makes more sound

@@8risk bullshit, looks better, tuning with speed density it performs better, and it makes less sound.

the carbon fiber doesn't make it go any faster

Very high, haha.

@@cobbtuning Sorry, protuned with the SF currently. I apologize for not being specific.

@@cobbtuning is COBB going to release a similar kit for the 2008 - 2014 STi?

It is! 50 State Legal, covered under our D-660-66 EO. ;)

@@cobbtuning Happy dance in Cali!

@@cobbtuning Holy! This is Carb Legal? :O Time for me to save some money for this beauty!
