Customer Reviews
Quick shipping, good parts
Got an Exhaust Manifold. It arrived in 4 days. Part looked good and fit my car as advertised. No issues with the order. Happy with the purchase.
Decent parts, some minor issues
I bought an Oil Catch Can and a Sandwich Plate Adapter from GSTP Auto Parts. The parts themselves appear to be well-made for the price point, especially the catch can which felt robust. Installation was fairly easy for both. However, the packaging for the sandwich plate adapter could have been better; it was just in a thin box and could have shifted more during transit. Luckily, no damage. Delivery took about a week, which is acceptable but not super fast. Customer service was fine when I asked a pre-purchase question about compatibility, they were quick to respond. Overall, a good value, but they could improve their packaging consistency.
Good quality, minor shipping delay
I ordered a Braided Fuel Line and a set of PTFE Hose End Fitting Adapters for my project. The ordering process on the website was straightforward, I found everything I needed without much hassle. Shipping took about 7 days to reach me in California, which was a little longer than I expected given they are factory-direct, but it wasn't a major issue. The parts themselves seem to be of solid quality; the braided line felt durable and the adapters threaded on perfectly. I haven't installed them yet, but first impressions are good. I had a quick question about installation and used their online chat support, they responded fairly quickly with a helpful answer.
Consistent parts and service
This was my third purchase from GSTP Auto Parts, this time I needed a new Downpipe. Like my previous orders for an Intercooler Pipe and a Cold Air Intake Pipe, the quality was exactly what I expected. The fitment was spot on, no surprises there. Shipping was also consistent, arrived within 5 business days, same as last time. It's why I keep coming back; I know what I'm getting. Never had to deal with returns or anything, so I can't speak to that, but for parts, they're reliable.

Hey, thinking about grabbing a downpipe from here. How long does shipping usually take to like, California? Need it kinda quick.
Just found this site, are their parts legit? Like, the 'factory direct' thing sounds good but wanna make sure it's not some sketchy rebrand stuff.
