I have a 2011 3.7 flex. Will these work without an after market tune?

 

Yes sir, no tune required.

 

all that money for not a whole lot of gain...

 

Just want it to breathe a bit better and have some improved "sound". I am assuming a gain of perhaps 8 H/P.
I drive a Highly modified Mustang [682 rwhp 577 torque] and have found the price for H/P is not cheap by any means. In my experience the cost of RWHP is about $30 to $50 per 1 RWHP. Cheapest gains are from the addition of a blower or turbo. Bolt ons nickel and dime you to death. The other side of the coin of course is you just can't slap on a blower without doing other work along with it ie: cams, exhaust,headers, suspension ,tires,gauges etc etc..Truck is my daily driver and grocery getter so I really don't want to go overboard with it as my wife of 30 years has already threatened divorce if I start "modding" it heavily like I did with the Bullitt.

 

Thank you,
we will be talking.

 

According to Airaid, with dyno results--- 20hp/ 39lb-ft. Shelby's and Terminators were all gaining these kind of numbers with just a filter change , so I'm inclined to believe it.

 

 

What does this do for the ecoboost warranty that from what I'm hearing is very easy to void?

 

^well, if you change it back to stock before taking it in for warranty work you'll be ok.

 

Yes, a highly modified engine that spins 6 grand, you might get the 20hp gain. But at what RPM? Thats the issue. The gains are at the 4500 to 5800 range. I never rev my truck that tight, because I don't need to. I would bet few people do.
If you look at the dyno results, you might also notice that at lower rpms, they actually are worse than stock, or the graph doesn't even start until 3 grand. Guess what, there is a reason for that. These trucks live between 1800 and 3000 grand most of their lives.

With the rpm range that these trucks live in, there are very few bolt ons that gain anything. And for the cost, it just doesn't make any cents.

If you want growl in front and roar in the back, then have at it, but don't think you are improving the performance by making it louder, because you probably are not. I love the rumble of a v-8. I like to hear them bark, but as I get older, I seem less inclined to spend the money to get them there.

 

^ I don't know about that. Their graph starts at 1900RPM and the torque kills the stock set-up to 3000RPM.

 

emailed you...

 

Nice looking intake and dyno chart. Thanks
