Are OEM products more expensive than aftermarket alternatives?

Investing in OEM ensures you’re getting parts specifically designed for your vehicle, which can lead to better performance and longevity.

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.
