sorry for the dumb question but answers would be appreciated

diverter for t7 cars, atmospheric for t5 cars

The twin piston bov is meant to help with idle on our motors and was meant to be able to be used on t7 motors. But the only type of bov that can be used on a t7 motor is a forge split-r valve which is part atmospheric and part recirculating and is ajustable.

so which one do i want for my car and what will it do

[markyboy75]

I'm guessing yours is a t5 as its a 99 like mine so you would be ok with a single piston valve. FMDV001GTI - Single Piston Ram Dump Valve . this is the 1 I use on mine m8 so take a look. Comes in different colours.

did this make ur pssssh sound louder than the stock one with an open air intake?

[markyboy75]

It makes a much louder noise than the stock valve. It's a definate head turner lol. Plus it makes mine smoother to drive, gear changes are smoother too. My valve was a good buy from ebay at £13 including postage.
