want to do some updates to wifes car, before i get to what i need i will tell you it is a 4cyl fwd triptronic, ( ok, get your jokes out of the way) now, i am buying a new cam follower and diverter valve with spacer( she likes the sound,and if it doesnt cause issues i will get it for her), also pvc fix, and a nice boost gauge that lights up with white # and red needle to match dash, i plan on changing exhaust and would like to do apr stage1. when looking up these items i find to many choices, so i am asking you( the experts)for the links of the best price on the quality replacement parts....
1.diverter with spacer maintnence free
2. cam follower
3. bsh pvc fix
4. boost gauge with pod, podi makes a pricey one and wouldnt mind a window mount.
thanks in advance, i want to buy asap
so far all i have done is lowered it with H&R springs and a set of gun metal VMR 708's 19in.

 

I don't think there are any cam followers cheaper than OEM.

I'm not aware of any manufacturers of window mounted gauges. Podi does the steering column, and the only other ones I know of go in vents. You'd have to do some custom fabrication.

 

ANd it will look like crap because it will never match the interior.... not only that you don't want to interfere will side airbag deployment
