Time to bump this. It'* a serious concern for the L27 and L36 with the plastic intake, as when the motor flexes, the filter could hit the top of the underside of the hood insulator, and go no further. The rubber coupler from Home Depot would exert all that force to the TB mounting flange on the plastic UIM, stressing it. Use a silicone reducer.

The L67 cars don't have as much to worry about, but it'* still something to do RIGHT the first time:

That'* a good visible example of what I'm talking about. The car is in gear (D), foot on brake, 3000 rpms, and no broken motor or trans mounts.

If you have the RX-4750 laying "flat" on an L27 and have it low enough, you wont hit the protector, but this is a good warning....Check ur filter/hood insulator for marks...

Correct.....the L27'* without the double washer tank should make an effort to install the RX-4750 horizontally if possible. SSE/SSEi with the headlamp washers don't have this luxury.

L36'* with the PCM behind the headlight will also be restricted to vertical position of the filter unless they relocate the PCM.

L67'* are the same way.
PCM right behind the headlight,so you'll have to relocate or just work around it.

Sure we do.....if your washer pump didn't work!


My silicone reducer flexes TOO much: it will not hold the filter up, so the filter lays (lightly) on the frame.

Right... Where did I get the idea the pipe was 2.5"? Ok, so change my comments to 3". Anyone have a good solution for a 4" filter flange to a 3" pipe?

Correct, but only the Series 2. The Series 1 L67'* PCM is inside the passenger cabin. But we have the double washer bottle.

Yes it'* a work in progress, but at the bottom.

What do you 94/94 L67 guys use for couplers?

I came across this intake on ebay and I was wondering if it would work with a 93 pontiac bonneville sse.

Has anyone had any problems or forsee any problems.
