Looking for help.

Update on this. The whistle is gone with this Cobalt deflector! Still have some engine noise but who doesn't want to hear their engine:-) The engine lid doesn't touch the rubber seal just a bad design.

I know we chatted or whistled about this

My K&N flame arresters did take the whistle away 90 percent from the Iac..maybe redirect air flow as opposed to a mesh screen??

But it pushed on on the merc 496ho cover and I didn't want to trim it. So off they came.

No performance gain btw.
Wonder if they'll work on Volvo.. I slightly get it with the 282 but it is very sound deadened.

Depends on the engine cover and sealing like you said.

I was going to go with the K&N . I don't know if mercury puts the intake air sensor on the back of the spark arrestor. Volvo does so the K&N wouldn't work.

Have it on my 2011 8.1 Gi. No whistle.

I saw that on yours awhile ago.
