is there any advantage to "upgrading" the stock bov? sound maybe?

 

Go with the Forge or Lindsey Racing one. The OE ones are prone to failure.

 

I use the evolution motorsport valve with the forge spring kit. It makes a fair amount of noise for a diverter valve.

I have a forge and it's never let me down

 

replace it when the diaphragm leaks.

this is what i went to. evolution.

I have teh evo valve, sounds bitchin

 

evo it is. for a change in sound.
thanks, one and all.

 

my stock one is making a fluttering sound...i wonder if that means it's torn.

 

yes the diaphram is torn.

 

I'm looking at getting a replacement too. I just ran across this site. they have it for $140, which was the best price I could find. Shipping is another $10, but it's still cheaper than most.

I have the evo. valve and can not here it at all with the stock afm, so don't expect to here it unless you have a maf.

Why are you guys putting a different spring in it? What good does that do for you?
Thanks.

 

Here's another, this site gives you the spring kit and free shipping at a lower price

Is this Forge valve plug and play on a stock 951 S? TIA

 

hey guys as a former Audi owner I have alot of knowledge on this particular part as it is a well known failure point on the 1.8T engines....

When I got my 951 I switched to the stock valve off my old Audi TT and it's been working great. I'd think unless you are running a modified car you wont need much more...but if you do go with a piston type valve just know that you have to keep up with regular maintenence or it will fail too.

AWE Tuning just launch this valve which looks like a good compromise to consider...as long as that diaphrapm holds up like they say it will it should be superior to the piston style valves..
