🔧 Dewhel Billet Turbo Resonator Plug Cover Cap - Silver for Chevy 2004.5-2010 Duramax Diesel LBZ LLY LMM: Product Review and Buying Guide Review

Too easy, remove the "6.6 resonator box" (a bracket). And insert the resonator plug into the hole. You can return the box to the fork or just leave the box to look at.

Doesn't fit. I had to install 2 new O-rings. Was REALLY free out of the box. Pay for a machined part and you still need to buy parts to make it work. Should have saved the money and just gone with a 2" Lowes fork.

I don't know if there are differences in the dimensions of the LBZ resonator hole, but this plug did not fit my Duramax 07. It fell straight without resistance. If it really fits, it would be great value for money. The finish is very pleasant.

Nice! Very easy to install. Takes less than 5 minutes, includes a picking tool (flathead screwdriver or 5/16" socket). A few drops of oil on the o-rings makes it easier to slide them into the intake manifold. The intake is more visible, but I love it. Pick Red, to tint the hood.

Seemed a little wider than it should have been. After lubricating the o-rings, I couldn't get past the first o-ring without trying to bend one of the o-rings. It looks like it hasn't been machined where it should have been and the locating ring groove may have been a bit small. Yes, it must be hard to push in and out, but this is a suction system that doesn't take on excess pressure. It shouldn't be that much pressure.

This was the best option for the money. I was embarrassed to spend $50 (after delivery) on a branded option and didn't feel comfortable with a $2 rubber cap from hardware stores. Easy to install. Uses a factory clamp which is very handy as the factory clamp has rubber feet to keep the clamp in the correct position on the fork. I really had to put some oil on the plug o-rings and after that it slid right in. My 2020 l5p started whistling a bit but not by a ton. But it is definitely noticeable…

Very disappointed with the fit of this product. I should have read other reviews and knew this part was better suited to the 2008 LMM recording. The part OD is undersized by approximately 1/16" (not measured. Manually calibrated only), or the o-rings are too small, the o-ring grooves are cut too deep, or both. Not sure what was supposed to happen, but this fits super sloppy. Apply silicone to the surface that will be in contact with the top of the intake elbow, wrap tape around the cap and OD…

Some people claim it increases the turbo whistle, I'm calling about that, I didn't notice any noticeable change in noise level or pitch while driving. When the change does occur it is so slight that most people would not notice it and a db sound level meter would probably be required to detect the change. I only bought it to clog a plastic resonator that is…
