Got a buddy selling a JLT Cold Air and I was considering buying it, but heard rumors that the factory CAI kit flows pretty good. He also said the oil from a filter like a K&N is bad for the mass air. Fortunately, this one is an oil free filter, but I was curious if anyone has put an aftermarket CAI on their 2011-2013 5.0 and noticed any difference?

If you get a cai you're going to need a tune. -
most ppl put a CAI in conjunction with a tune.
but from what i understand the majority of the gains come from the tune itself, not the CAI.

I had the car tuned yesterday and the tuning isnt so much the issue. A guys selling one for $200 and I figured Id get it cheap since its not that old, but I just wanted to see if Im wasting $200. I keep hearing the factory CAI is pretty good....Comment

At the power level you're at right now, the stock intake works just fine. Like most CAI's on bolt on cars, they are more for looks and noise than actual power production. As was stated earlier, the majority of the gains come from the tune.Comment

It just depends on which CAI you get. A lot of them increase the size of the MAF housing (JLT for instance) and so that is what makes it necessary to have a tune in conjunction with adding a CAI.
From the research I've done in other forums, the AirAid CAI seems to be the preferred choice to give the best/cleanest MAF readings/tunability on both manual and automatic cars along with the fact it doesn't require you to get a tune if you use their optional MVT insert that comes with the kit.
As far as gains from the CAI itself, probably around 5-10hp at the flywheel at best. The stock airbox setup is pretty decent, but it can be improved upon. It's just not going to net you a massive amount of power just by itself though, especially on a mostly stock car.2011 Mustang GT - California Special - Black/Black - M6 - 3.73's

I did a JLT, BOSS 302 manifold and tune. Went from 378/360 to 419/378... It also added 600 USEABLE rpm of power (peak moved from 6,600rpm to 7,200rpm) YMMV.Originally posted by PGreenCobraOriginally posted by Trip McNeelyComment

Gear Heads (Travis) tuned it. not an ounce of driveability issues and he never moved off base spark (seems that timing is the cause of canned tunes failing #8 piston)Originally posted by PGreenCobraOriginally posted by Trip McNeelyComment

Yeah, the clowns doing canned tunes tried to jack up the timing and claim massive gains. Unfortunately it grenaded a lot of motors in the process. That's why a custom tune is always the way to go when you are dealing with a motor like this.Originally posted by DON SVO View Post2011 Mustang GT - California Special - Black/Black - M6 - 3.73's

If you only put a CAI on the car then no you won't feel any difference. The difference is in the tune.2010 F-350 6.4L SRW CC 4X4

The reason for #8 failures is NOT tuning. It's a piston issue from Ford, hence the redesigned pistons for 2013. The '11-12 pistons are weak, and will burn up on even a stock tune. Ask me how I know. It's also why even a modest tune was killing them early on.
I'm fairly certain Ford has figured it all out. That's why the service replacement engine for '11-12 cars is 2013 spec, and includes a '13 tune with new parameters that didn't exist before (cat overtemp protection is one, I know there are others).
I haven't heard about any '13-14s blowing #8. Have you?

I honestly think it was a combination of the two issues. The piston is somewhat weak from the factory and the additional timing and subsequent detonation takes care of the rest.Originally posted by 46Tbird View PostThe reason for #8 failures is NOT tuning.

I would agree, if only cars with tunes were breaking pistons. That's not the case. Yes a tune, with more aggressive fuel/spark/RPM, would exacerbate the issue, but that photo above shows that even a stock tune would do it.When the government pays, the government controls.Comment

Anybody running a CAI actually notice the Air Inlet temperature being reduced? When I veiw the air inlet temp on my gauges it is either the same as the ext air temp or 1-2 degrees warmer. A different CAI may produce more air flow.... but I doubt you are actually going to get any benefits of "colder" air entering the engine. I have also heard stories of these voiding warranties. So take them off before ever going to a dealership service dept. Of course, if you have ever put a tune on the car the engine warranty is out the door from what I understand.Comment
