I get that sound without an after market dump valve lol. The foam around my air filter is still there, nothing as far as I can see has been changed at all. I'm lucky in the sense that my T4 gives me the blow off noise without fitting after market stuff.

Btw if you do a search you'll see these cars don't really get on with dump valves...They're good cars but they aren't half fussy the T4s as you've found out with your spark plugs!
