Forge intake pipe

Some slight modifications to the car and the cold air heat shield was needed but otherwise it fit great. Can really hear her breath now!

Very nice!

Love my new side markers - very clean looking and unique in how they flash when turning left or right. The only suggestion I’d make is provide instructions for both installing them and for being very careful with the wire once you disconnect the old light housing Left side went in ok, but I lost the right side into the fender black hole which required me to remove the tire and unscrew most of the lining so I could find the wire!

Great fitment

I bought these to replace another set of lug bolts I had recently bought. The original set had kind of sharp and badly cut threads which would become overly tight in my wheel hub even when torque’d to spec. These Nuespeed wheel lugs were machined well and have been much nicer to take on and off. A little more expensive but, worth it to not worry about snapping a lug when removing the bolts anymore.

Great sound!

Paired this with a malian downpipe on my 225 roadster and it has a fantastic sound. Lots of turbo noise too.

Much better braking

I was considering just upgrading the brakes altogether, but I decided to try red stuff brake pads first. They are exactly what I needed.

Beautiful and amazing fuel pump upgrade for my MK1 Audi TT

Works great

I’m using these in my 8J TT with some Defi gauges. It requires some disassembly of the stock pods to use with these pod adapters, which was the most complicated part of install. Works great. The pod adapters push the gauges out a little further than the photos represent but I found it acceptable.

Works great

Have had one of these on my 8J TT RS for a few years now. Works great. Installation takes just a few minutes. I only needed to use one of the three available tap ports; I used blue loctite to help ensure the plugs don’t back out (or fall in).

I like them!

This product is fantastic! The smoked side markers look incredible, and the sequential leds are a huge upgrade. Installation was a breeze truly plug-and-play and I had them on in minutes without any hassle. They really modernize the car's look. Highly recommend!
