Originally posted by playaman But the stock airbox draws in air from behind the FR headlight, nowhere near the PCM. As far as I understand it, and can see, the stock intake doesn't draw air into the engine at a position which would cool down the PCM. Also, I'm not blocking the grille or air dam w/ my intake so I'm not sure as to what you're saying. Please clarify as overheating IS a concern for me. Thanks.
You probably have an earlier model Seville. Sometime in the mid 1990s (not sure of the exact year), they moved to the PCM to the underhood area. Fewer wires this way, plus the PCM stays cooler...as long as its in the flow of intake air.
That's a picture of the setup with the PCM under the hood. That large silver metal hunk visible through the hole is the PCM's cooling fins. You wouldn't believe that the Northstar can suck 300 horsies through that hole, but it really does work! They spend lots of time and money to perfect the system.
Note, that picture was taken when I had the cone filter. I've since took it off and put the airbox back on and have been happier overall with it.
sal, are you talking about the link i posted earlier. I dont know whats wrong, i havent had any problems. One thing, if it isnt working, you may have to log in. Try that. Sometimes in order for it to stay logged in, you will have to enable cookies.
And WATER! Watch those PUDDLES! That thing is right inline for spray from other vehicles, driving rain, and worst of all, puddle splash from your own tires! I hope your engine doesn't hydrolock! The quality of your system looks good, but I'd seriously consider relocating that filter.
