is APEXi a quality drop in?
 

Is the APEXi a good quality drop in filter? The pictures make the quality look flimsy and cheap but A LOT of people are running them for their engine and APEXi has been a JDM brand for a while,

Thanks

Not sure about APEXi, they are a big name but cannot speak on their filter. I haven't seen too many 86's with their filter though. I would just go with K&N or Cosworth. Can't go wrong with either of those.

EDIT: I have a Cosworth drop-in. $40 bucks, can't really beat that

"Compared to the AC, the K&N “plugged up” nearly 3 times faster, passed 18 times more dirt and captured 37% less dirt."

interesting.

I went with Cosworth. I actually bought a K&N before but never got around installing it. Decided to sell it after some internet searches.

Use the oem filter and replace it more often.
"This illustrates the apparent trade-offs between optimizing a filter for dirt capturing ability and maximum airflow." from http://www.nicoclub.com/archives/kn-vs-oem-filter.html

Apex'i is a high-flow paper filter and for years was the best one out there: http://www.supracentral.com/foundati...on-kit-review/


AEM dryflow wasn't around at that testing, but it's pretty damn good as well being a dry synthetic media. I'd never use an oiled filter on an engine using an air metering device as they can get damaged from the oil.

one thing to take from the test is that while the K&N did not filter as well as the others it did flow better. Also you have to look at other factors that could not be tested. for example our 86 intakes have a tube in the bumper that does not face forward. this in it self will likely reduce the amount of dirt particulates that get to the filter it self. I'm willing to bet that they directly applied (for a lack of a better term) the test dust to the filter and not threw a tube with a 90* bend in it facing away from the direct flow of air. what im trying to get at is that the filters probably wont see that much dirt that fast unless you drive threw a dust storm :bonk:.

Another thing that i noticed is that while the K&N filter did become completely restricted early on in the test it took close to the equivalent of more than 2 cups of a mix Confectioners sugar and powdered milk dumped onto the filter (assuming i found roughly the correct sizes of powdered milk and confectioners sugar). I look at it as if you keep a K&N filter clean it will work pretty well.

take all of this with a grain of salt though cuz im no engineer.

on a side note that Wix filter they used in the test looked to be the close to the best of both worlds. good flow with decent filtration.

I'm using the APEXi drop-in filter now and it works quite well. I was using a K&N filter before but didn't like how it was oiled. It's all personal preference though.

Oiled air filters need abit more care especially during re-oiling. Apply too much and you risk damaging the expensive airflow meter. I chose a dry type filter because it's easier to clean. Just rinse, dry overnight, install.

When you swapped from the k and n did you clean the MAF or did you just drop in the APEXi and call it a day

The latter. I didn't have to clean my MAF
