It's that piece thats attach to the blue box with 2 screws. The pipe and the bent piece that extend to the battery area is still off. The only probem with this is that the car just suck in hot air, how ever even with the pipe the air would still turn hotter and by the time it get to the same area it might have the same temp. NEXT test.......a 88' K&N filter in my 89. Hope u guys are right about the 88 filter fitment on 89

Tuning a stock WRX/a turbo KA engine is easy.........intake,exhaust 20+HP but with the stock 89 sentra and a $100 budge(willing to spent).......it's a challenge.
