Review on HPS HTSVH5 REDx25 Temperature Silicone Pressure by Daniel Gilbert

After trying this product in my automotive, I was severely disappointed with the results. Despite the manufacturer's claims this product did not improve the performance of my emission system in any way. The only positive thing I can say about it is that it was relatively easy to install... Overall, i would not recommend this product to anyone looking for a genuine improvement in their car's performance..
