Cold air intake options

I got a spectre (aka sphincter) today for $107 from Pepboys. Sounds great. Power increase is barely noticable. Overall quality is ok. The filter seems kinda wonky and not very filtery. Its bo K&N but well see how it does.

So this simple mod makes a huge difference. I think it payed for it self today !!!!! So for the people who say they don't make power and don't do anything for gas miliage SHUT UP FOOLS.

I didn't think it would have such a big effect as it did. The throttle response in much better. From 50km to 80-100km the pull it has is greatly improved.

OH and the best part!! I was down to 15.2 mph in the city for the last bit. I got up to 18.2mpg !!!! Took a pic when I didn't think it was going to get any better. But it did View attachment 66865Here is what I thought was great. Then it got better.

So a few pics from the drive View attachment 66867View attachment 66866


This cheep ass kit is #1 in my books.

LOL ... good enough for me! I'd been looking at that CAI for awhile ... undecided but the DIC ... yeah our 2004 Denali 6.0 absolutely refuses to move off of 15.6 average MPG!!

Good enough for me, next payday CAI here we come!

There is a thread here with dyno results on most of the popular models and they show gains of anywhere between 2-5 HP so if you think you can feel that , great! As for mpg, I doubt you are actually seeing a measurable improvement. I never trust a DIC for accurate gas mileage and I bet if you do a real fill-up to fill- up calculation you'll see you didn't gain anything unless your old air cleaner was extremely plugged up. I sure didn't gain any mpg when I installed mine, probably dropped some due to the fact it made me put my foot into it more! But it does look good.

Well there is always that but as I am want to say, I'm kinda like.:



If a CAI can budge my DIC off of 15.2 ... I'm good.

I`m not sure about all CAI kits but it`s important that you check the elbow coupler on the throttle body every now and then. I have a spectre and it has loosened and came off sucking unmetered air into the engine. I have found that it happens more in winter time, Probably from heat cycling. You will find out quickly that the engine does not run very well like that. I just check it whenever i open the hood.

The right foot factor made the mpg go way down this weekend lol. It does look good and does feel better. As for mpg it's still ok even doing 80mph and having some fun. Was 18 back to 15.5. But that's ok. The smiles were worth it

You guys that can get 15...congrats. With my aggressive BBP tune on my 6.0 and the fact I seem to feel the need to beat every single car all the time, I get around 12 but that's almost all city driving. But it's damn fun city driving.

LOL

I was pleasantly surprised to average 17.8 mpg on a recent road trip.

But if I cared so much about fuel economy, I would not have bought a Tahoe.

LOL ... so 15.2 mpg does seem to be the thing??? I tend to have a heavy foot getting up to speed ... "apparently" getting there quickly ... comes at price?? I saw 9,8,7,6 and lifted!! ought I was thought I was going to be outta gas before I got 20 miles!!!

The good news??? If everywhere I went was downhill ... I'd get 33+mpg!

On a side note ... I'd heard these things have 98 mph speed limiter?? In as much as the tires are not rated at speeds over 100 mph, (2004 Denali), I had "assumed" that if I got close to that 98 mph, .. it would cut fuel or something??? Apparent not ...97 mph passing and no indication that it was going to stop accelerating?? A bit of a surprise there ... I was not looking at the DIC at the time.

On my 03 with 4.8, using the GPS, I hit 103. Wouldn't go any faster, guess the fuel cutoff kicked in .There's a thread on here somewhere if you're interested about top speed .
