Installation difficulty? EasyTotal time: ~.5hoursDISCUSSION: This is a simple upgrade that anyone can do. Keep in mind that there are several ways to go about doing this and several kits available on the market. The kit that I bought came from Rotary Performance and it included everything that I needed for about $130 bucks. You can also fabricate the parts you need and buy a cone filter for a total cost of under $50 bucks. I believe the best product currently on the market is the Apexi Kit for around $140 bucks. The only problem with this kit is that it only fits the 89-91 cars. Whatever route you take, the whole point of this upgrade is to get more air into the engine. To do this, we need to remove the restrictive stock air filter and the air box that dominates the front right corner of the engine compartment. INSTALLATION: Remove everything. The instructions that come with the kit are simple but compete. In a nutshell: You remove the entire air box from the car and disconnect the hose that goes to the air pump. On the bottom of the air box is the Air Flow Meter. You need this so you remove it from the box. You them mount a small bracket on the meter and reinstall it back in the car 90 degrees from the position that it used to sit. Finally you slap on the K&N filter and install a smaller air filter on the air pump. The finished product:
RESULTS The increase in HP was nothing to really write home about. I could definitely HEAR the car sucking air now. The next step for improving the intake is to build an air box that separates the hot engine compartment air with the cooler air drawn from outside the engine bay. The point of this is that cooler air is denser and will allow more O2 into the engine.
