Dont waste your money...Yet...Do something to free up your exhaust flow first, and then get a larger MAF before upgrading the throttle body...As it is, the MAF is too small for the intakes currently available, and the stock tb is pretty much maxed out size-wise with the MAF...If that last part made sense...Any bigger is a waste right now...Until your exhaust and MAF flow better, any other intake mods are pretty much a waste...Your intake can only flow as much as the most restrictive part...Which, save for the factory filter contraption, is the MAF...
The PZEV has a plastic tb (not sure about the Zetecs), but there is maybe a milimeter or two to gain by boring it out...Nothing thats going to make any kind of real difference, though...
...And now that Im done confusing you with my rambling...
