Review on Injen Technology SP1977BLK Intake System by Tony Francis

Took about an hour to install. It took me longer because I read the instructions. In fact, it wasn't all that hard to need. He could have a good illustration showing where the pieces hang. So far my fuel economy has gone from 26.3 to 27.5 mpg. I'm not sure if the performance is higher. Yes, I've hit him a few times, but not often before that. Whether it's stronger or not, I can't say. I will say that acceleration is more like a car going downhill. That is, not stronger, but it feels like the engine can rev up faster. I'm pretty sure that means more power in the engine bay. It really reduced the amount of clutter in my 2012 Nissan Altima 3.5 coupe. This prompted me to remove the motor's useless shield as well.
