Not cheap enough for you guys? I thought this would be in demand. Easy bolt-on horsepower and you can retain all the standard intake system if you want. Obviously I have not run this myself, but if it's like the Accufab (& I can't see why it wouldn't be) the gains are very worthwhile - crisper throttle response, more power and desn't have that strangled feel at higher revs.
If it's of interest please make me an offer, as otherwise I'll have to list on Ebay and let the Mustang owners bid.
