Let customers speak for us
from 348 reviewsLittle tight fit I had to relocate my power steering reservoir other than that really happy about it

arrived on time. took no time at all to install them both (30 min) THANK YOU

Order arrived on time and was as described. Also had question and received a email back in a quick and timely manner

Good quality work best budget harness for a swap easy to install cat runs great with it

Great product, shipped quick
Would recommend to my friends 10/10

Customer service is great, replies were very quick! The manifold is like a piece of art, welds is nice and solid, mounting flange is thick, this is a compact piece. They even cleaned up the ports, and I can't believe the price was so affordable compared to others.

Good product and fast shipping and affordable

Very happy with this valve cover. Fitment was perfect, it bolted on easily with no leaks or issues. It's priced fairly, on par with a second-hand AGN smooth cover, but being brand new makes it a much better option.
Delivery from the USA to the UK was quick and trouble-free. It arrived well packaged and in perfect condition. All in all, a solid product and a smooth buying experience. Would definitely recommend.

Used to find them everywhere now you need a company that has the parts you need.
Queda en perfectas condiciones con subaru 2015-2021 lo recomiendo

You guys rock I had a question and you guys answer them immediately that is very important communication with your customers thank you you guys are very professional

Great quality

Excellent fitment with the ability to run 2.0 FSI/R8 coils with no adapters. Cover fits timing belt cover and uses OEM outer hardware. Comes with a very nice oil cap and additional hardware for the center studs. The two -10 ORB fittings for the PCV system make it an additional bonus. Much better then the OEM AGN valve cover I have been running for years.
