Well, Twiggy and I got our hands on a stock 4cyl BA hatch today..

After tearing it to shreds, and cursing several "typically mazda" things.. we worked out how we have to do what we have to do. Have a mockup of the CAI sitting in the back of my car right now... looks really good. Clears everything comfortably, and we made the mockup out of oversized pipe to be sure of fitment when the 2.75in pipe goes on... Mockup doesnt foul anything so the real thing sure wont either.

We spent a great deal of time cutting various lengths of PCV to ensure a minimum number of bends, thus getting the shortest possible cold air pipe we could make....

Air filter goes where the intake resonator currently sits, in the side of the front bar on the passanger side. Does mean front bar removal might be in order for installation, but its not overly that hard, once you figure out where all the bolts are!

Next step... our 3D dude is going to get to work getting some technical drawings so we can take hte pipe to a place with a CNC bender. We've decided that we're going to bend the lower pipe out of one piece, rather then welding 2 pipes together. Single pipe is going to be marginally more expensive, but removes a weld, removes alot of the cost of welding wire and gas, and should mean that our turn around time on orders is much faster.

So hopefully all those with BA's who were interested are still interested! we should have pricing in the next week or so.

We're going to build a real prototype, out of mild steel cos its cheaper, to test fitment... once thats built we'll need a BA hardtop to play with to see if its a straight fit, or whether we'll require a different bracket.

Stay tuned....
