Hi guys, just a quick couple of q's about refitting the standard recirculation valve to my 2003 blob wrx (i pick it up may 1st). Currently its fitted with a Bailey atmos dump valve, i have ordered off ebay a 2nd hand recirc valve off a 2003 sti, is it safe to assume it will be the same as the original?

is it just a case of unbolt the bailey, remove bung, fit oe recirc valve and attach vacuum line? As much as i want to keep it i can't justify the insurance premium hike from 424 standard to 698 with a dump valve!

Keep the dump valve and don't mention it to the insurance. Any queries come up in the future tell them it came with the car you didn't know what it was. I never declare small mods like that, its just an excuse for them to get more money of you

I don't really see it any more of a mod than a set of speakers- it doesn't make it quicker etc, its more just there to look/sound pretty!

Exactly, hence the reason not to notify the insurance

Only issue with not declaring is in proper accident when you have no opportunity of swapping to original & vehicle gets looked at buy inspection engineer you run risk of insurers giving you the middle finger & voiding your cover.

Playing ignorant don't work either, insurance companies love people who do it as it like giving them the cover money for no cover.

Shop around as a fair few specialist insurers would not want extra for those sort of basic changes.

recirc is best on MAF sensors anyway really, if you log the MAF readings & fuelling with wideband you would see why.
