Just picked up an Ingen Powerflow intake system here locally for $150! Guy took it off his Titan and had it cheap so I jumped on it. Installing tonight so I'm pretty excited. Was going to get an intake anyway but this was a killer deal, supposedly only has a few hundred miles on it, looks new, at this price we'll see!

Awesome you got a great deal! Tell us what you think after you take it for a spin!

here's a tip: spring for the extra filter from injen when you by the cleaner. It's only $50 and you won't have to wait for your filter to dry before you can drive your truck. :D

i love my Injen

Well, so far I just took it for a spin around the block. Not too loud, can barely tell its there until you step on the gas, definitely a lot livelier! Will get to test around town tomorrow and on freeway. So far, I LIKE! I was so ready to buy one online and then it popped up on Craigslist and a few hours later, I'm taking it home. Install was ok, some scraped knuckles putting it in but pretty easy. My engine cover barely cleared the intake but it fits pretty nice. Will post some impressions tomorrow...

Hooo Yah!!!! How about some pics of laid down rubber?? :D

Well, so far so good! Throttle response is a touch quicker and smoother up through the RPMs. Before there was a slight hesitation when you were cruising and then dropped the throttle to pass or speed up, now it's much more linear and the acceleration just keeps going... If I drive normally, there's not too much difference, it's when you step on the skinny pedal that the fun begins. Also, the noise difference isn't too great either, the Injen is fairly quiet but has a bit more growl at about 2000 RPM and up. Nothing intrusive, but we'll see in the future as I'm now looking at exhausts. Took some pics, I'm only missing one part, the vibration damper that goes underneath the bolt where the powerbox bolts in. It's on there good now, but not level, will hit an auto parts store later. So far I'm pretty happy at my investment, anyone have any suggestions now for what exhausts to look at? : )

I've seen good opinions posted about the Gibson. Some of the Titans have also had good results from the JBA.

A few pics of my install...

looks awesome! I want one but I will need to run up on a deal like yours before I get one.

Nice!!!! Glad you like it! But you got it dirty already! LOL!!!

It wasn't new so that's why its a bit dirty, plus it gets dusty as anything out here in the desert so the engine bay is always covered with dirt. Ah well, it's not a show truck, as long as it performs!

Installed the Injen over the weekend... drove normal for a bit to let things acclimate... and then...

When I stepped on it, it sounded like a bunch of friggen tigers were wrestling underneath my hood - I'M LOVIN IT!!!

I want to schmob on the gas all the time now!!

P.S. Big thanks to Jason B for hooking me up too! :)

Took a trip to LA last weekend, the mileage took a hit from the intake. I used to get about 15 mpg around town and maybe another or two on the highway, after driving about 600 miles mostly freeway, I got about 14. Oh well...

That's kind of interesting Derek, on my trip from LA back to Canada, I averaged 15.5 mpg doing 80 mph for 95% of the time but the best mileage was the first 2 leaving LA and then after I met you. After that I am assuming that I got into winter gas.

After hearing that you dropped some mpg, I don't think I will be getting an intake for awhile.

Hmm, well, after being back in town at work for the week, I filled up with 87 octane, drove normally everyday for work, filled up again and found my mileage at 15.85 mpg over 350 miles. I'm going to keep track more closely, but it definitely seems my highway mpg have gone down. Not sure if everyday performance is so different, but cruising at higher speeds (70-80), there's a noticeable gain in passing power and acceleration.

I came across this last night on a website from a guy that does custom tuning on GM and fords and this was in his tips for increasing gas mileage


7. Decrease AIR !! . This flies in the face of what is sold out there today, but if you can decrease the amount of air entering the engine (due to the fact that this is a closed loop system as of 1996 OBD2) you will use less fuel, too. Ideally, you want to maintain the same horsepower required to combat air friction, rolling mass losses, etc...but do it with LESS AIR !!
Let me illustrate. A closed loop system maintains the air fuel ratio at 14.7 lbs air to 1 lb of fuel. This is maintained for idle, cruise and in some cases, even at wide open throttle.
If you have 60 grams/sec air entering the engine at cruise, you're using 4.08 grams of fuel per second. If the cylinder pressures are increased without creating harmful exhaust byproducts, or if these byproducts are controlled by the catalytic converter, we can gain mileage by decreasing airflow through the engine while enhancing the spark curve to maintain the same rear wheel HP.
On the chassis dyno, we can get vehicles down to 45-50 grams air/sec maintaining the same air fuel ratio, and same wheel HP as stock--and the overall result is less fuel consumed ! 45 g/secs works out to 3.06 g/fuel used in the same time period--or an almost 25% saving. We can't gain this in all vehicles of course--this example was resultant data from a 2007 6.0L HD 3500 GM truck.
This flies in the face of every aftermarket product out there claiming that it saves fuel--you will never gain mileage by increasing airflow through a gasoline engine in a mass airflow type system.
Because we carefully remap the spark curve with a remapped ECU, we in effect are increasing cylinder pressure without adding fuel. Increased cylinder pressure translates into more useable torque and power to maintain the power required for 'rolling resistance' of the vehicle down the road. The increase in horsepower often results in better fuel economy--although we do not guarantee mileage gains--as we cannot determine how YOU drive, and what your driving habits are.

Sounds like all he is doing is a timing advance.

its natural, more air taken in, need more fuel to mix.. = mpg goes down.
