Daystar KU20041BK Universal Firewall Boot, (Pack of 5)

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.

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

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.

Absolutely perfect for feeding accessory wiring through the firewall or body panels. You can cut back the tip to get a larger opening. The rubber is flexible so forcing too large of a wire through for a tight seal is easy. A step drill bit is extremely useful to achieve the proper hole diameter and is very short making it easy to fit in tight places.

Single Boot arrived in OEM packaging with the part number for 5 pack of boots. Instead of five, I got ONE. To get a refund I had to send it back and buy single items to make up the number I needed. Cost me an additional $40+ to get what I wanted. That's more than $20 per boot. NOT HAPPY. Alan

wish they made different hole sizes ( mount opening )
