3.3TT DIY intakes w/Heat shielding drop about 0.2sec off 0-60

Im on the team saying that this mod is probably mostly for looks and sound than actual performance. @ less than $100 its totally worth it. I can't imagine spending the $500+ dollars on a branded intake system though, even if they are marginally better

I just don’t know if the car needs all this, engine temps at idle are less important than rate of iat drop once moving. IMO I’m starting to think he stock box will allow a quicker temp drop as it literally is the only cold air intake of the bunch due to the sealed system. I’m really uncertain what way to go. Can anyone verify a true performance gain over stock box?

Dyno’s I’ve watched seem to show verrrry little gains on any of the setups, but catbacks literally grabbing up to 20 hp/tp.

This question has been answered many times in multiple threads and if you look at the small 1”x2” air inlet connecting to the air box as well as the flat & even smaller entry inlet behind the bumper you will see why the OEM intake is so restrictive.

There are many dyno results showing ~15-20whp peak & across the RPM range and up to ~45whp near redline where the the stock air box restrictions cause a big power drop off after 6000rpm. Here’s just a few dyno results showing intake power gains.

Also, the couple YouTube dyno videos showing no or very little power gains is because they didn’t do 4-5 WOT runs to allow for our ECU to adapt to the increased airflow. Tuners have confirmed our ECU takes a while to adapt and doesn’t start adapting until WOT.

Lastly, many Stingers including myself have confirmed about 0.2sec drop off from 0-60 or 1/4m times by just adding intakes.

Bottom line, there’s no doubt that our stock air boxes are very restrictive and that adding open air intake systems definitely increase power & performance.

Does anyone who has done this think there is room for a larger oval shaped air filter?

My AIT drops rapidly when giving enough throttle to hear the intake. When I hear the sucking air sound, the AIT will literally drop 5 degrees in one second a lot of times. I wager it's very effective over stock.

I don’t see anyone using the other spectre 9732. Is there a reason why? Is an intake of that size detrimental to performance or is it just overkill and you won’t need it?

There is no way that would fit. 9.5" is a long filter. The ones most people are using are in the 5.5" range and fit perfectly in the void left by the stock airbox.

Good call. Seems to be similar size, just not sure if it’s worth it.

There likely isn't much of a performance increase with the larger filter but the sound will change. It makes sense in that JT design to go with a larger filter because there is space for it. That kit and the Injen one comes with new piping that replaces the stock rubber ones. To do it as a DIY with the Spectre filters you'd have to find an aftermarket pipe with a similar design to Injen/JT in order to get those Spectre 9732 filters in there.

Yes! And he uses extreme angles back to fit that large filter.

So I tried to keep the stock box with the Spectre filters to help with heat. Passenger side is done. Dremel cropped out on the drivers side so I’ll do that later.

Very cool! I put heat shield on the frame of car to block ambient heat, you should add.
Looks good!

a little creativity works well.

BTW forgot to update on mine. When I pointed the intakes forward (towards headlights) my temps actually went up significantly. Putting it back towards the inside of car and keeping lower half of intake box maintains 30-40 degrees lower temps for some reason. My high AIT's are now like 120 ish normally, when it was other way I was getting to 150-160!

Make sure the ac is on and the fan will run. Running fan provides fresh air..

That may explain the BMS intake design.

Got the drivers side done.

very creative !!

Totally. A+ for creativity. Not for the faint of heart as there is no going back to stock with that solution!

Slight necro, but, just joined the DIY team. I used straight joiners and managed to make 5" filters fix extremely snugly with almost no movement but still enough to allow for engine movement. I'll be adding a pair of conical heat shields one I pick up hose clamps that will fit their extra diameter.
