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

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.

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.

Pretty tough non-silicone rubber coupling that fits extremely securely on 4 inch OD. Good Stuff!

Truth that they are soft and could use some reinforced material and maybe just me, they seem to slightly harden once heated then soften once cooled. But only true 90 with short snout to fit tight areas. This is on Chevys TBSS stock throttle body.

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.

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