drop-in filter vs intake?

so i run a fastman TB, a magnaflow exhaust and the SCT. ive been looking around at intakes and was wondering if running a free flowing or "performance" drop in filter would benefit me as much as an intake? i was looking on wkjeeps.com and theres a PN for a performance filter for the stock airbox. i also know that companies like AFE, K&N, etc. make drop-in filters for the stock airbox that increase airflow while maintaining the stock system.

just wondering if i could benefit from a drop-in as opposed to a intake? is the difference THAT significant? thanks for the help

Re: drop-in filter vs intake?

you mean a ram air/cold air vs. stock aftermarket replacement filter..... i've had many ram air setups in previous vehicles and didnt see any significant gains, so this time in the wk i just got a AFE replacement filter for the stock airbox (but i also dont plan on doing any engine/performance mods)

Re: drop-in filter vs intake?

You might get a little more out of an intake. Will it be a perceptible difference, probably not. Will there be an audible difference, definately. So I'd say it's all preference. Personally I like the throaty sound of an intake, but to each their own.

Re: drop-in filter vs intake?

On second look with your mods, an intake couldn't hurt. Might as well finish what you started with your breather type of mods. Just one smucks opinion.

Re: drop-in filter vs intake?

I made a custom intake using the stock air box, K&N drop in filter and K&N 63 series intake plenum. I removed the shield on the intake thats behind the grille and modified the K&N plenum to replace the accordion style intake plenum and box. I think mine is a better setup then the full CAI kits because it truly draws in cold air where as a cone filter even with the shield still brings in a large amount of heat. I might even heat wrap the plenum and box one day.

It has since been painted black.

Re: drop-in filter vs intake?

I service it ever 3 to 4 oil changes and I change my oil every 6k so ever 24k miles give or take a few. I check it regularily and if its dirty sooner I clean it, if its got dead bugs or big junk in it I gently shake it out.

I deff noticed a snappier throttle response after putting the filter on a stock intake and even more so after doing my plenum. That made the biggest difference.

So yes it passed the butt dyno. Also I highly recommend a flyin ryan bored TB.
