What do you guys think? Think I could get the same benefit from just dropping in a K& filter element into the factory air box? Still need a tune? Thanks!

May want to do some research before plugging in a K&N filter on your Boss. They come with a decent low restriction filter stock. CAI and a tune may be a better but more expensive choice.

Drop-In K&N filter - no tune necessary (just drop it in). Not much HP gain, if any.
CAI without tune - as far as I can find, only a couple CAI's that say they can be installed without a tune. The others highly recommend/require a tune...just adding the cold air may lean the motor out a bit too much for comfort.
CAI with a tune - most expensive option but will produce the best HP gain.
I started with the K&N drop in just because it is an inexpensive option that flows a bit better than the stock filter and just needs to be cleaned and re-oiled every once in while. At some point, I will go with an intake and tune to get the best gain.
I didn't dyno "before" but mine made almost 400 rwhp SAE corrected with the K&N and side pipes opened up which is on the high side for a stock Boss.ArizonaGT said:I have a Dyno graph showing the exact opposite, with the kn picking up five hp or so for about 1000 rpm but no change in peak hp
C&L has a wealth of info on their site and is worth reading. The stock system is restrictive and, in fact, flows 50 cfm less than the factory 4.6 setup. The difference in feel with a high flow CAI is obviously highly subjective but the gain can be measured. Last summer C&L sponsered a free dyno day. They would do a baseline pull, install their CAI with the no-tune insert, and then do another pull, or in the opposite order, if preferred. They guaranteed at least 10 hp.hdaniel said:I installed the C&L no tune required CAI...ordered from Americanmuscle.com...look great, don't know if it will result in any hp increase (12 hp claimed)
