I like the way the 90 looks over the 87. Let us know how it performs

It fits the engine way better! I wonder why they even made the 87.
The smaller size tps makes it look more sleek for sure.

I had the battery disconnected when I swapped to reset idle settings and when I cranked it, fired right up smooth and sat around 500-600

Negative. Intake has 90mm opening. Straight bolt on. Took less than 5minutes.

This is the 90mm sitting on top of the 87mm. So you can see the difference.

Any issues with the Intake tube fitting over the new 90mm TB? I've got the AirAid MIT on mine right now and its tight on the TB.

This seems like a pretty cheap and easy mod. How does it help with driveability? Is there a performance gain or more of a support for other and future mods?
