The Best Places to Buy Performance Parts Online in 2025

Written by Stephen Ebersole, Founder of Autoficial

You are here because you are searching for modifications for your vehicle. When shopping, you have run into confusing and overwhelming information. You find your turbo kit, exhaust system, or coilovers, yet dozens of online vendors are offering the same ones. It is around the same price, and you need to make the right choice. As a car enthusiast myself, I’ve spent hours — sometimes days — bouncing between sites trying to make the smartest choice. That’s why I built Autoficial: to simplify your research and help you buy smarter and upgrade faster. It is important to know where to buy parts and why it matters. In this guide, I will break down my top 10 most trusted online vendors for performance upgrades in 2025 and how to make sure you are getting the best deal. 

1. Why It Matters Where You Buy From

Not all online auto part vendors are created equal. Beyond price, for the best deal, you must consider the following policies: 

• Free Shipping –  Imagine you found the lowest price on a turbo and you’re super excited to order it…but didn’t notice the $75 line item that reads “shipping fee”.  Suddenly, the best deal becomes the most expensive deal. 
• Average Shipping Time – What if you have a build scheduled for the weekend, but your parts won’t arrive for 10 days? Now your car is stuck in the garage and you are stuck with rescheduling or paying more for expedited shipping. 
• Return Policy – When your part doesn’t fit which you didn’t realize when ordering, and the vendor only gives you seven days to return it and charges a 20% restocking fee. Now you are out of cash and stuck with a part you can’t use. 
• Guaranteed Fit – Imagine spending hours to find the perfect part. You order it. It arrives and it doesn’t fit.  You try to return it and the vendor says, “Sorry, you ordered it and it is your responsibility.” They may accept a return but you’re stuck with vendor credit and limited choices.
• Performance Upgrade Advice – You drop $800 on a mod that doesn’t give you the power you had hoped. Without expert advice or recommendations, you risk wasting money on parts that slow down your build…or worse, damage your vehicle.
• Warranty – What if your $600 coilovers fail after three weeks. Then you find out the vendor will not back them up with a warranty? You never think to check on part warranties until it is too late. 
• Price Match – You like a specific part from a vendor but the price tag is $100 higher than another vendor selling the same part. You suck it up and order the more expensive part only to find out later the price-match policy.  You didn’t see it because they don’t like to advertise it.
