Collection: Engine Performance

Happy with the outcome of it installed! Great product. Great costumer service after I reached out on a concern about the product.

Product is as advertised. Can't beat the price or speed of shipping.

They give amazing customer service, also good quality products, I’d recommend to anyone

Factory pins were really on there well so I only used the outside connectors and guides. The pins slid into these connectors with ease, the guides went in just right and the assembled connector snapped perfectly onto the ignition coils.
Product appears to be well designed and solid.

Always good to have shipping insurance for those unexpected moments

Good quality product everything fit where it needed to

Absolutely awesome product. Fitment is good, finish is sexy, showing the machining lines, and it’s just beefy. You’ll love it, just buy it. 2001 Audi TT Quattro 225hp AMU, non VVT

Exactly what I was looking for!! Amazing quality and fast shipping

Although my part was just an o2 spacer it was well made, arrived quickly, and I liked it’s packaging

Got this harness/sub harness and shipping was quick. Looks great quality and labeled for easy install! Customer service was a great help with all the questions I had.
Note:-- this harness has already bypassed the vtec pressure switch so it has no plug for it! I had to do some research to find out but don't worry if you see no plug

Very high quality harness, very well labeled! Had a few difficulties installing, but after contacting customer he quickly walked me through every step and had it fixed in no time. Also the "customer service" was the owner contacting me himself! That should speak for itself! Will definitely be a long time customer.

Exactly what I needed

Great customer service

As soon as I turned it over, I saw a huge difference in the way it was running! Buying again when needed.
