I have a 2011 4dr wrangler and am looking at cold air intakes. I have heard they will increase hp and gas mileage. Does anyone have any suggestions or experience they can share?

 

HAD an Airaid, sold it to put an AEV Snork on - loved the sound my Airaid made, but no gas mileage improvement. Might have had a bit of HP increase, as I ran my stock filter for a bit before I got the balls to cut my hood, and she was slow to the punch. Gas mileage went back up with with snorkel and K&N drop-in.

Bought Airaid for $240 - great sound/mild HP gain

I BELIEVE a TB is about $100 - total cost for you is $350+

Sold Airaid for $160 - OUCH

Bought snorkel and drop-in for $390 (Northridge and Amazon) - bottom line, spend the extra $40 and save yourself from locking your engine.

 

Very true. Be that as it may, I got bored over the winter and installed a Viper throttle body and open element air filter on my Heep. I like that way it sounds, throttle response seems better, and because of the way the ECM controls fuel delivery at WOT, it probably makes more power then.

I also have no worries about hydrolocking because the bottom of my filter is higher than the OEM intake and I will not drive in deep water.

Anyway, the bottom line is, if you want to do it, do it. Just don't expect a tangible return on your investment.
