Injen IS Series Short Ram Intake Reviews

Tremendous improvement over the stock airbox

Reviewed By Timothy M (ROUND ROCK, TX) Reviewed for a 2003 Acura RSX —9/14/2014 1:43 PM

I purchased the Injen intake to replace the stock airbox not for increased performance but because of a broken output nipple on the stock unit. I chose the Injen because it has an Amsoil filter. The build quality is robust and it's absolutely beautiful. I'm thoroughly pleased with my purchase.
