This is for Magnuson/Arrington Super Charged cars only. I had this on my 5.7 (09 Charger) for about 3 weeks and went a different route. It is beautiful and really opened up the breathing for the Manguson. I paid over $400 w/tax & shipping. I'll sell it for $350 shipped.
If you are running the stock airbox with the Magnuson SC and you are this CAI you should re-tune as this really affects your AFR since it draws much more air.
