Hi Mark,

We have never released the type-s bov with a black cap. They were produced only in anodized purple. I'm sorry but it looks like you purchased a counterfeit.

Thanks!

Do the single spring mod 1st, It also allows for an easier install since there is no need to connect the lower vacuum port.

bro ayoi,

what will happen if i dont remove the small spring? and din connect the lower vacuum as well?
Can i just plug n play? i read the link u gave me but dont really understand since nvr exprience it with m sqv b4. mind to explain to me in much simple way?
thx

bro avaultz,

Let me explain in simple way
Without single spring mod - connect upper/lower vacuum port
Single spring mod - only connect upper vacuum port

*My experience b4 single spring mod (i connected the upper vacuum port only), my BOV flutter chu chu chuuu sound.. after single spring mod shhhiiiingggg sound :)

hmm.. my sqv only got 1 vacuum hose. that y im curious where to get the 2nd vacuum hose for the lower flange?
and will i get the shiinng sound instead of flutter without single spring mod - connect upper/lower vacuum port? tq

if the single spring mod is not done, the valve should have the lower vacuum port connected to a source still pressurized after the throttle plate closes (IC pipes) and still have a very light adjustment to allow for the easiest valve actuation possible. Failure to connect the lower port while keeping both springs inside will make it difficult to open on small pressure changes, and even more so if the spring is adjusted tighter.

Settings - Both Springs (Greddy Default)
Result - Will flutter unless the lower vacuum port is used...and even then sometimes. Loud whistle without the lower port, little whistle or whoosh when using the lower port depending on throttle change and air flow.
