I wonder, after you're done making this heatshield and sealing it around the filter.. is it really that much better than a stock SVT airbox?
I've gone through the KKM, K&N OEM drop-in, monsterflow foam filter (with and without the SCA CAI), the now-defunct SMA CAI, and now I'm back to the stock airbox again. Admittedly the KKM was without a heatshield, but really the only noticeable difference between any of these was sound level and a lighter wallet...
