Ineffective Filter, Waste of Money

This air filter did not meet my expectations at all. Automotive performance was not improved and I noticed no difference in air quality. After I put it to the test, it failed miserably. The only positive aspect is that it was easy to install. However, at this price point, I expected much better performance. Don't waste your money on this subpar replacement part.

Pros
  • Easy to replace and install
Cons
  • May require frequent replacements due to being multi-purpose and not specialized for specific pollutants

Suitable for 2019 Subaru STi!

Fits my 2019 STi perfectly, just like the OEM filter. Didn't notice much of a difference, POSSIBLY a little more intake noise, but it could be a placebo. You do not need any additional engine tuning to use this filter as it does not change the intake manifold diameter or MAF position, you can be 100% sure of that.

Pros
  • Air Filter
Cons
  • Modern

Fits 2020 Subaru sti

My auto parts store doesn't have 2020 sti air filters so I'm going with k&n for now so it feels good, same as the stock air filter because it's good I think a bit louder , maybe actually here is my current turbo winder lol but definitely there if you are trying to save money! Remember to clean the MAF sensor every time you clean the air filter and you should be fine.

Pros
  • replacement parts
Cons
  • obsolete
