Got them in the mail the other day. They look good, basically exactly the same dimensions as the OEM pieces, but made in poly.






Once it all goes back together, their blue color won't be so obvious, but it makes for a cool little accent.

Shd look great - thanks for the quality check
Are they slightly grippier/offer more friction or less than stock iyo?

I was a bit surprised w/ the durometer of the poly they used, since it is slightly stiffer than the OEM rubber. I don't think it'll cause a problem sealing once they're clamped into place and might actually offer a more secure grip against the intake popping out once installed.

new word - thanks

Durometer is one of several measures of the hardness of a material. Hardness may be defined as a material's resistance to permanent indentation. The durometer scale was defined by Albert F. Shore, who developed a measurement device called a durometer in the 1920s

your intake and hardware looks superb in white - did you have to do any special washes/dips etc..
before powder coating went on?

It's all plastic (late model plenum), so just plastic primer, base coat, and clear coat.

From experience I can tell you that very few will handle the long term underhood temperatures without deforming! Which is the absolute last thing you want happening to anything attached to your intake manifold.

Thanks Jason ... Back to you V - is that a bubble on the blue one or a drop of water?

Did you install these and how are they holding up

I have contacted the seller a few times and never received a response so I am wondering if they have withdrawn this product from the market in view of Jasons comments above..

Never heard of using polyurethane for intake components. Usually see silicone stuff. Wonder how it will hold up.

I installed them, so far so good, no complaints. I emailed them about some of the molding defects (see Jason's post above) and they sent me a couple of extra sleeves that were free from defect.

Can't believe it's been 2 years already ... so V how they holding up?
Does oil impact them much?

They should hold up better to oil and chemicals better than rubber. Curious to hear the results.

Interesting to use Poly vs Rubber.
Do they seal well, or are they a softer poly than say bushings?
That's one benefit to rubber.
