Perrin [15-21 WRX/STI] Firewall Grommet
The PERRIN Firewall Grommet makes cable management for routing wires from the interior to the engine bay simple and protects them from wearing on bare metal. It allows for an easy pathway to route cables, wires, and hoses between your engine bay and interior, making for a more professional installation when installing PERRIN gauges. Without a grommet, wires can rub against sharp metal edges in the firewall and wear through - the PERRIN Firewall Grommet keeps solid and clean connections.
- Fits 2015-2021 Subaru WRX and WRX STI (legacy range - see notes)
- 1.4-inch (35.56 mm) grommet - protects wires from rubbing against sharp firewall metal edges
- Keeps solid, clean gauge wiring connections; simple installation in about 30 minutes
- Part #ASM-GAU-120
- Prop 65 Warning: Cancer and Reproductive Harm - www.P65Warnings.ca.gov

FAQs
Please read our FAQs page to find out more.
Are OEM products more expensive than aftermarket alternatives?
OEM products might have a higher upfront cost compared to aftermarket parts, but their superior quality and durability often make them a more cost-effective choice over time. Investing in OEM ensures you’re getting parts specifically designed for your vehicle, which can lead to better performance and longevity.
Can I purchase OEM parts online or do I need to visit a dealership?
You don’t need to visit a dealership to get OEM parts. You can conveniently purchase genuine OEM components from authorized distributors and reputable online retailers like Turbo Tech Performance. Our online store provides a wide selection of high-quality parts delivered straight to your door.
Are parts from brands like Mopar, ACDelco, and Motorcraft interchangeable between different vehicle brands?
No, parts from Mopar, ACDelco, and Motorcraft are typically designed for specific vehicle brands. It’s crucial to ensure compatibility with your vehicle’s make and model by checking part numbers and consulting with a knowledgeable expert.
Can I install OEM parts myself, or is it better to have a professional handle it?
While some OEM parts can be installed by DIY enthusiasts, the complexity of installation can vary. For the best results and to ensure proper fitment and performance, we recommend having a trained mechanic install the parts, especially if you’re unfamiliar with automotive repairs.
Do OEM parts come with a warranty?
Yes, many OEM auto parts come with a manufacturer’s warranty that covers defects or issues. Be sure to check the warranty details for each part at the time of purchase, and keep your receipt for any potential warranty claims.
