Review on Injen SP7029P Polished Technology Nano Fiber by Trent Moua

As a loyal customer of Automotive performance parts, I was excited to use this Emission System component in my car. However, as a result of using this product I found that it caused my car to have decreased power and a rough idling .The installation process was also difficult without clear instructions. The only positive was that IT added a slight increase in fuel economy, but it was not worth the negative impact on my car`s performance. Overall, I would not recommend this product..
