It's pretty easy to install...but I'm going to be honest I'm taking this post down. If you want it I'll sell it $125/obo issue is the charge tube around the mass airflow sensor is wider than the throttle body it causes a cel to come on because the mass airflow sensor freaks out when there is to much air passing over the maf sensor. This is on my 1.8L sonic after I got a tune and the maf was adjusted in the tune it was fine to use. It's very throaty and you can hear the air getting crammed into the engine. You pickup a decent topend pull with this intake system and I did gain 2 mpg after the recalibrated tune
