This is "not" hard plastic.
This elbow is "not" hard plastic. It is flexible material (rubber like) and fit and functioned just like we wanted. Used it to make our own cold air kit on an LS engine in a 1964 Chevy El Camino. The description states PVC and most think that is hard plastic, this is not. It is very flexible and can be trimmed if needed. I would not recommend using in boosted applications (per manufacture as well) as there apparently is not any reinforcement woven into the material.

Perfect fit
Perfect, perfect perfect

Perfect for the home builder.
If you look close you can see that it is not equal length. This worked out great for getting my turbo inlet tube in just the right spot. It is a 90 both ways but there is about 1" difference in length depending on which way you put it.

Perfect for tight spaces
This worked great for an LS-Swap in a small engine bay.

The angle is perfect but it does not fit around my 102mm throttle ...
It is what I needed.... kind of. The angle is perfect but it does not fit around my 102mm throttle body like I thought it would. Took a little stretching but it makes the opposite side a little deformed. I though it was plastic but it's rubber which is fine it's pretty thick. All in all It will do.

works great just a little thin
need to curve away from fan blades and very little room on an LS2 swap works good just a little flimsy had to re enforce it...

They fit perfectly
I needed a tight radius elbow for my LS swap. They are good quality and worked awesom. I would buy them again.

Not practical at all.
Good in the way of it fits in tight areas but it’s not strong like reinforced silicone hoses. It’s basically a soft compound rubber that collapses on cold side of turbo when turbo is spooling up. Very disappointing.

Tight 90 deg elbow
This elbow worked perfect after wasting my time and money on others. I have an Ls swapped 240 sx with a Holley ultra low intake. The throttle body is 4” away from my rad. This 4” elbow was able to stay 4” diameter and 3/4” off the rad. Definitely worth it.

functional
definitely a little flimsy, probably wouldnt handle boost, but it looks nice, and works fine for my N/A intake
