Frequently Asked Questions

Are 'universal' automotive parts truly compatible with all vehicles?

While many accessories like pedal covers, seal strips, and GPS speedometers are designed for universal fit, performance and electrical components (like the HEI Distributor or battery terminals) often have specific compatibility requirements based on the vehicle's make, model, and year. Always check the product description for specific fitment details before purchasing.

What is dielectric grease used for in automotive applications?

Dielectric grease, such as Permatex 22058, is a non-conductive compound used to seal out moisture and prevent corrosion on electrical connections, including spark plug boots, battery terminals, and wiring harnesses. It ensures a strong, reliable electrical connection and extends the life of these components.

Can I install a Heads Up Display (HUD) myself?

Yes, most aftermarket HUD units are designed for simple DIY installation. The models listed typically use a USB plug and GPS signal, requiring no complex wiring into the vehicle’s OBD-II port, making them perfect for home installation.
