CH4b's are great intakes for a mild street engine, like any dual plane, they have thier limit. To me the plusses are: Better performance than a stock iron intake, ALLOT lighter than the stock intake, will fit under most hoods with factory air cleaners, and if you grind off the CH4B and other non factory looking digits, paint it orange, and you'll have an intake that very few people will even recognize as anything but an old original iron intake.....Stealth is good
