I went with the cai , I had a sri on my 90 teg, and after i drove it for a few minutes in the summer heat the engine department was like 1000 degrees and the whole point is performance so why suck all that shitty hot air up? As well ebay has nice ones that are decently cheap Trendspeed makes them for the b18a/b that are like 26 bucks they come with any colour filter you want and have the plugs for your vaccuum lines, then when you get it go to your performance store and get an aem sticker and pow 300 dollar cold air intake for 30 bucks
