Description

The Big SF Intake for the 2015+ Subaru WRX is constructed of full 3" aluminum tubing, a custom aluminum airbox, and a dual cone intake filter. Mandrel bent and powder-coated black, the 3" intake tube and custom airbox look great in the engine bay and increase airflow potential substantially. The reusable Green filter can be cleaned and re-used for the life of your vehicle!

Note: Proper tuning is MANDATORY for this intake!! Use associated +BigSF OTS Maps or have your car tuned by a Certified Protuner


Why?

Replacing the factory intake and airbox with the COBB Cold Air Intake will greatly reduce pre-turbo restrictions. When a restriction is removed, it allows the engine to be more efficient while also enabling it to make more power!

Subaru Big SF Intake System WRX 2015-2019 is rated 4.7 out of 5 by 49.
Rated 5 out of 5 by from Good quality, straightforward installation Installation wasn't bad. Although we're in the era of tablets, it would have been handy to have some paper instructions. That's my only gripe, though. The product is great, and the sound is borderline erotic. I'd definitely do the "from the bottom" installation. A floor jack will give you plenty of room to work. Pro Tip - Be sure you didn't let your friend borrow your floor jack and jack stands before you tear your stock intake off.

Rated 3 out of 5 by from good product but fitment issue with MAF I bought this a year ago this may. It all fits well but the MAF. It leaks. I had my cobb pro tuner double check with a smoke test. We believe its from the powder coating preventing a good seal. We were able to seal it ourselves but its definitely an issue.

Rated 2 out of 5 by from AF Ratio is usually off First thing I noticed about the intake was that the intake had metal shavings attached to the inside. I had to spend some time and effort to remove it all. After I installed it, it was very difficult to put the box cover on due to fitment issues. My biggest concern is with the placement of the filter. Due to the design it can be very difficult to place the filter at the correct position on the intake tube. You can try to mark it but this doesn't always help as the filter can be canted and not squarely secured to the intake tube. These slight variations in depth and canting can lead to huge changes in your AF ratio. It takes me hours of driving and tweaking to get it between -9 and 9.

Rated 5 out of 5 by from Killer BOV Sound! Just did the install today. Very straightforward, and with the access port, was able to quickly flash the proper map. This thing sounds like a dragon. You can hear it in action, and when the blow off valve releases, it makes me smile every time. Solid purchase and we'll worth the money.

Rated 4 out of 5 by from Not quite the fitment I expected I decided to install from the top which is completely doable, having a small ratchet helps. The quality of materials is top notch but I had a terrible time trying to line up the mounting holes for the box and being able to get the lid on. It felt like I really had to torque it to be able to squeeze the screws in. Definitely more challenging to get in the I was expecting.

Rated 5 out of 5 by from Wicked in 1st gear! Everyone...I put this thing on my '17 WRX...she's got about 5,500 miles...so just broken in.....I have COBB's cat back exhaust...great product....really freed up the turbo...spins up faster and reaches much higher rpm without the restrictive stock exhaust...and I already had the 93 Octane stage 1 flash on the car... But when I put the big SF on and re-flashed (make sure you re-flash...you won't believe the difference)...this thing became a monster...First gear is WICKED....it just pulls so much harder. I also have the Group N transmission mount...keeps things where they should be. MAKE SURE YOU FLASH..I made a mistake and did a real time flash...I flashed again today (the right way) and just had to make a comment here...this thing makes a really big change...yes it makes noise..but people won't hear it for very long ;)

Rated 2 out of 5 by from Have had nothing but rattling I bought this 3 months ago when it first came out and I honestly have had nothing but problems. I hit a bump one day and it started rattling. Was able to get it to my rattle by recently it has started back up and can not get it to stop to save my life . There should be a bracket in the middle between the intake box and the turbo but there isn’t. I have taken it to have it looked at and they can’t seem to find the rattle. I have even tried seeing if it wasn’t the cold air intake, put my stock back on and then no noise. Very disappointed since i paid so much for the product.

Rated 5 out of 5 by from Amazing Sound Interesting install. The instructions could be better (PDF? Is this 1992? Where's the video?). Other than that, amazing quality and sound. Better throttle response, gas mileage (unexpected), did I mention the sound? I have the CVT and now have the woosh that we all want. Never thought I would have it with an auto. Decent AP map as well. Thanks Cobb.
