Agreed. Stillen does make the best hp gains, but what you read on here about short rams gaining "nothing" is not true. IMO, an aftermarket intake allows for smoother acceleration and improved throttle response. There are power gains as well, but if a short ram make 8 whp and a stillen makes 18, can you feel the difference? Butt dyno's are more a measure of torque anyway, and the only thing that will give you noticeable torque gains are forced induction. Even with an intake, header, and full exhaust with ecu tune you're only going to gain about 20-25 lb-ft of overall tq to the wheels. It will be noticeable, but it's also at least $2000 without installation and tuning fees.
Replacing intake hoses and K&N drop-in seems to be the cheapest intake mod. Stillen makes the most gains but also has the most cumbersome installation and requires removing the bumper and using dremel tools to allow for proper fitment of the intake pipes. I really like the HKS intake but the price is outrageous. HKS makes quality parts but that's a bit much.
