Tight fit over K&N
Barely fit over K&N system 57-6005 (K&N filter RX-4750, see photo) but it fit great once it's on!

Fits! Spectre 8.75" cone filter
Spectre has several cone filters but the 8.75" length/height cones seem to all have the same taper. I have the 9732 filter and this cover fits perfectly. I did some tests with water on the cover but not on the filter so I could see what passed thru. I also tested this from a vertical point, not from the side or below. If it takes a direct hit, it will pass thru. Rain drops (tested with sprinkling water on the cover) did not get thru and pool up. Gentle splashes mostly pooled up but some got thru. Considering the results and a real world application, this should deflect most water since the hood and overall engine bay will not allow a direct hit. Mine is a bit more open from the bottom but I'd be comfortable with water splashing it from about 1 foot or more away. Any less and I'd have to be careful/considerate. All in all the fitment, function, and price are all appropriate. I'll def order another as a backup since I live in the AZ desert. Pro Tip: If you don't tailgate, you don't get dusted out as much ;)

Snug as hell
I measured both my intake and sock both came out to came size but it is a big snug tight but just be careful not to rip it so it gently. Overall looks sexy and fits good keeps dust out and particles

MUST HAVE FOR A OPEN FILTER
Absolute must have for open filter without enclosure. This will keep the filter very clean for much longer. The sock is simple to remove and clean. Saving alot of time compared to removing entire filter then waiting to dry.

Tight Fit but works
I used this to cover a MOPAR cleanable air filter that was being attacked by mice, yes mice, they were eating the filter medium. Since I put this cover off the rodents have stopped chewing on my expensive filter.

Fits on Injen Evolution EVO1500 Filter
Fits on the Injen Evolution Intake -EVO1500 for the 2016-2021 Honda Civic 1.5T. Which is awesome because even if Injen makes their own filter socks, they DO NOT make one that fits their own filter. But I'm glad this Spectre one fits and was cheaper than the Injen products.
