the fuel pumps look identical but online it says it wouldn't fit.

This is the fuel pump on the 3IS looks similar to the pictures posted here in my opinion

You'll know for sure when you try, not that expensive. This wasn't even designed for the GS, it was designed for the LS high pressure fuel pump, but it fits because they use the same fuel pump.

Default Not too much different

I just installed both covers (taking out the battery helps a ton for space in the engine bay, at least for me lol) on my '08 RWD GS350 and it's sounds the exact same tbh. I was really looking for the 30-50% reduction like others had said but not too much of a difference tbh. Maybe it's a placebo? :/

Best, Norm

It either helps reduce the noise or it doesn't . Maybe people are expecting too much.

A simple decibel meter app would answer this , because numbers don't lie.
