## Customer Reviews

### ⭐⭐⭐⭐⭐ Great for any type of wiring installs
*by C***. on March 13, 2022*

These are great for installing radios, lights, or anything that requires a new hole in your firewall. I'd like to see them be a little bit thicker rubber, but they work perfectly fine as they are. I've used several on different vehicles over the past few years, and haven't had any issues so far. I like to add a little silicone where they meet the firewall, to help hold them in place and ensure there won't be any leaks.Great product. I highly recommend them.

### ⭐⭐⭐⭐ Expensive.
*by S***M on October 4, 2013*

Worked great and are the only good firewall grommets that I have found. That said these are WAY over priced. Seriously 10 bucks each!

### ⭐⭐⭐⭐⭐ Just what I needed.
*by R***R on March 25, 2019*

I added power windows, power door locks and a kickin stereo system to an older ford pickup, so I had a bundle of wires and a lot of power draw. These boots let me route power through the firewall, through the cavities to the door with every transition looking professional and avoiding the bends normally associated with running any power to the doors. Great product.
