Who makes quality cone filters? Options

[Xander_X]

I haven't purchased an aftermarket intake in years so I don't know who the goods brands are now. I have a drop in for my stock 91 Legacy Sport turbo, so that was a no brainer. I wanted to make a custom black aluminum intake pipe to replace the factory one in my Celica and use a cone filter. BUT I'm going to retain and customize the factory box so it will look close to stock. K&N and HKS I know, I don't believe an HKS dome style filter will fit in the factory box. I don't think Injen or AEM make their own filters (last I knew). Anything new out there I should be aware of?

Oh boy, There has been many tests for after market filters and intakes. To start, drop in oil filters are bad for your car (mainly if you have a MAF) and there are no gains between a drop in and a OEM filter. Secondly, intakes just add noise...sweet, sweet noise but noise none the less. The majority of cone filters that you can buy are crap. People think og more power but they never really think of the "filter" part in air filters. My top options for a cone filter consist of AEM dry flow filters and True flow foam air filters.

I've seen many more but these guys are pretty entertaining while being good.

My suggestion to you is to modify the stock system. keep the stock box and replace the stock tubing. Do that and youll have a good sound, and proper filtering.
