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

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. I'm wondering if the standard horn and airbox limit the sound? However, this is a great option for the money.
