Vibrant 4.5' MAF adapter + cone fitment Q

[oplix]

I wanted to buy a new cone filter and maf adapter to replace my stock air box and was wondering if a 4.5' inlet cone (5' diameter) would have any clearance issues?

Also how restrictive is the stock intake pipe?

You won't have any clearance issues at all but I'm not sure if it'll fit the stock intake. The stock pipe isn't really restrictive but creates turbulance. I would get an aluminum intake pipe to go with that filter. You can go on eBay and get the entire kit for about $40 shipped.
