Great dry filter option for the 2019+ sti
Here’s the deal, only 2 companies make specifically designed filters for the 2019+ sti redesigned airbox. The previous filter designs for 2015-2018 sti are a hit or miss on fitment and I have personally tested: blitz (doesn’t work at all for 2019+ sti airbox the thing won’t close) K&N (great filter but oiled and power band can feel choppy? at times.. - only other company with 2019+ sti specific filter design) Apexi - fits the airbox but does not feel like a proper fitment, if you don’t believe me experiment with one in a 2019 sti and see what I mean - good filter quality though and does basically fit but very tight close. And now...I’m running a Grimmspeed drycon. Smooth power band. Designed similar to a k&n but looks like a lot nicer filtration design good material as described by them. Excellent perfect fitment in the airbox for a 2019+ sti. I will say it’s not audibly as “wooshy” as all the other panel filters I’ve mentioned. It’s kinda quite like the apexi with the k&n being loudest. But this one makes a little faint intake noise over stock and apexi & honestly thats cool plus the car feels nice and stock with it and rings out the rpm range real nice. It’s washable which is also a plus and I’m glad there’s a few ponies from it more than likely as highlighted in their testing for the sti. Great stock airbox panel filter option. Don’t hesitate just get it instead of a stock genuine OEM one and give it a shot like I am.
