Stinger Firewall Grommet (PG12)

Worked Great

I used this to run b4 gauge power wire through a hole I drilled in my firewall. It was very easy to install and works as intended- the wire is protected and my firewall is otherwise sealed.

What you need

The right way to run 4GA power through your firewall. Easy to install, solid secure connection, protects the wire from damage (you don't want that shorting out to your chassis!), and seals the inside of the car from the engine compartment. The only part that might be a challenge is drilling the 7/8" hole required - I used a step bit and a right angle drill and it was a piece of cake. Excellent product at a super price.

Decent voltage meter

I've had the meter for a few days now and it seems to work as it should. Not anything impressive, but then again it's a pretty simple component. The only bad thing I can say about it is how bright it is at night. The numbers themselves aren't too bright but the stinger logo is just blinding. I put a piece of electrical tape on the back side of the cover so that it wouldn't show through anymore and now only the numbers are visible. It's perfectly bright now.

Great price perfect for upgrade

I am routing all my amps separately because upgrading to 4 gauge low oxygen wires this is perfect for very quick install

Ditch the rubber

This was a must to run the thick wire through the firewall. No more worrying about the old rubber grommet going bad or leaking. Much easier to install too.

This Thing a Gigantic

I was surprised when I got this just how big it is. I ended up just running the 4 gauge wire through an existing rubber grommet that was unused by Toyota.

Cool product

Super cool product to use and it looks much more professional than those rinky dink groumets at auto stores
