DIY: Improved Airflow DCI
I installed the BMS Dual Cone Intake this weekend, and I had a bit of a OCD moment with regards to the direction of the air-flow. So, armed with some long zip ties, I devised this very, very, very simple solution.

Lol.....you are not the first to do this mod.
I used a coat hanger....ghetto I know! In regards to air temps. I have been logging intake temps in 72F weather and find that at constant cruise low throttle around 2-3K rpm my intake temps sit around 89 to 90F. During WOT my temps drop as low as 86 during a full 3rd gear pull from 3K rpm. Not bad for a DCI setup. Even with a cold air intake setup, your ambient air is going to pick up some heat travelling past the turbos. I had the stock CAI on last week and noted about a 5 degree improvement over the DCI's at times, but the DCI's are less restrictive and have better throttle response. They also pull a little harder at higher rpms which is where to stock CAI restriction becomes more of an issue. A CAI might be better at heatsoak recovery though, since you would be pulling in cooler air immediately to help bring the intercooler temp back down. But I found that I could get my intercooler back down from 106F to 89F just by using half throttle or so for a couple of gears. The key is to get airflow into the intercooler. This is with an aftermarket intercooler though. |

As far as the heat shield / temp issue, I have a FMIC so it's kinda moot. The people I trust (with data) say that the increased flow outweighs the heat - and the FMIC is more important for hot climates than intake. I think the AFE looks better, but I didn't think the extra dollars were worth it. After installing the DCI, OCC and FMIC - I'm done with power modifications. Downpipes and exhaust aren't worth the hassle and if I decide to spend extra money on the car it will be for the suspension. |

I have to agree that the AFE looks better but for the price the BMS DCI is a better buy IMO. I disagree that the sound difference is minimal. Especially with a JB3 on you will have a brand new awesome sound you will love, if you want to improve the sound I think the BMS is the best bet at least from what has been reported on this site.
