I love AEM products as they are very good quality, well built products which will last years.

Excellent quality and it works great!

Very fast afr response time, installation was simple, and overall quality is great

Amazing quality

Horrible product expected much better quality and thought it would last at least a month

, sensors are obviously not manufactured well nor quality tested

Good quality, easy to install and comes with a sticker that gives your an extra 25kw!

Packaged very nicely and product is of strong quality, looks exactly as it does in the image

As well as Q,A section

It works as it should.

Worked as it should, helped me tune my 300C to the perfect spot I want.

Worked as it should.

n’t buy it unless you like lighting your cash on
