I purchased a used racing beat elbow intake and I did not care for it. It removes all possible use of a strut tower brace. I compared it to my jackson racing intake and power felt less. There was no fun at 4,500 rpm.
It also changed the sound of the car and I was not particularly fond of the sound. The closest thing I could come up to a description was a wet fart.
It sounded raspier, than it did a growl. This was because the air filter was no longer shielded and was exposed.
Out of a ten I would give it a 5. Not that great but if you want a different sound then go for it.
