Installing a top mount intercooler. It has a 1/2" nipple on it. There's also a 1/2" nipple on the accordian hose. Hoping to use these two connections for a Bosch/Saab recirculation valve.

Most BOVs appear to use a 1" hose, would reducing to 1/2" be an issue at stock boost levels?

Thanks!

Nah, will still work fine at low boost. Probably will make a higher pitched sound.
