I was looking around for an intake for my 04 cavi Z-TYPE, but it seems their is only two brand names the make them Weapon R and I forget the other. Is there any other brands or intakes for a different car that will work well.

whats a Z type?

You have the 2.2 and a VLX with the Z24 bodykit. You have something that wasn't available in America but only canada. They haven't had the Z24 sincs 02 although the canadian on is only what you have but another 1500CDN$! Cheaper one don't ususally fit as well! you could try www.rsmracing.com based in toronto, probably the best for GM tuning in North America. www.carmodifier.com has the inlen intake although you have to call for the price. They are in Ottawa.
and www.jbodyperfromance.com based in TO do their own intake for the EcoTec. The Short Rams follow a similar path to the 2.4 intakes but I don't know if it would be an exact fit although not far off!
