I installed the system on my Opel Omega B and I was quite impressed from the intake. The power has had a tangible increase. I recommend this intake system to all who are hesitating!!!

I put the 57i kit onto my Vauxhall Corsa 1.8 SRI 2004. It sounds great.

We just purchased the filter for our 2007 Opel Vectra and the result comes in a snap! Better traction and faster response! I recommend your products everyone.
