Re: K&N Air Intake System--Worth the $? [m_boise] by srlbotanical by z71bill

I know - many people really think that they get better performance & HP from the K&N filter - could it be that replacing an old "dirty" filter (used truck) - with a new filter could have given you the same result?
 
If it really increases 2 MPG why doesn't the manufacturer just put it on at the factory? - GM, Ford, Toyota, Nissan & Dodge would KILL to get a 2 MPG bump in their full size trucks.
 
First - I have has several VERY loud cars in my life - so I do understand -
 
But if you really think about it - it's like putting baseball cards in the spokes of your bike - sounds real cool - but does it make you go any faster?
 
If I only new that the 1951Bowman Mickey Mantel rookie card in my spokes would someday be worth $800.

I don't think I'm getting better day to day performance at all from the K&N Intake system--only very small changes at wide open throttle...which is not how I want to drive. The jury is still out on mpg though. I've heard so many conflicting reports on these things that I figured I would spend the $250 and get a real answer for my truck in my driving situations. I have no problem taking the stupid thing off if I see no gains and a dirty throttle body.
 
As for the exhaust--it sounds more like a "truck" now, and the sound was 90% of the reason I added the fart can. The change in mileage that I saw with the aftermarket exhaust was real...maybe it was from the environment, gas quality, or the fact that I added it before reaching 2000 miles--maybe the engine wasn't really broken in and performing. Who knows? Sounds better and the dual look (no real function) gives it some uniqueness.
 
Manufacturers adding mpg boosters? They are all in cahoots with oil companies anyway---otherwise we would be driving around for free using our own garbage for fuel by now These vehicles are built to be non-offensive and meet government regulations while still costing too much and sucking enough gas to keep the fat cats fat.
 
Anyway--enough rambing...just want to make it clear that I'm not here to promote any kind of product or aftermarket stuff, just wanted to hear from others' experiences and let others know of mine.

I noticed that. It's the Crew Cab bed. Haven't checked to see if they shortened the wheelbase any. If not, what's the point? The model with 20" wheels sounds like a model Chevy had last year.
I just looked and the wheelbase is that same looooong freakin' 143.5". But the truck is almost 10" shorter. Whoopty do. The thing I hated about mine was trying manuever with that wheelbase. And that's one thing I love about my Av. 130" wheelbase!

They had to have shortened the wheelbase.
 
So in the 1/2 ton lineup you can now get:
standard cab, short box
standard cab, long box
extended cab, super short box (from crew cab)
extended cab, short box
extended cab, long box
crew cab, super short box
 
I think the idea behind the addition is that some people want something with more space than you get in a regular cab, but don't need as much space as the crew cab. They also want a usable bed, but don't really need anything too large (sort of the average homeowner that just wants to be able to tote the mulch home without dirtying up the car trunk). This combination improves over the other options by meeting both requirements with the shortest possible wheelbase / turning circle in the lineup. It will provide the extra convenience of the extended cab truck without the "boat"-like manners in tighter spaces and should still give most of the other benefits of a 1/2 ton over the compact / mid-size trucks. Things like overall payload weight and towing capacity.

I think it's a good idea. Ford started, this but do NOT sell many extended trucks with the super short box. I wonder if these 20" tires and several box size options are a peek at "things to come" with the new the 900 GMT line, out next year?

According to the Spec's right here on Edmunds ALL the X cabs (6.5' and 5.8' bed) AND Crew Cabs (5.8' bed) are still 143.5" wheelbase. No improvement there.

Edmunds has been known to have incorrect specs before. Given that the crew cab truck has the same wheelbase as the extended cab short box right now, there are 10" being cut out of the ec ssb truck. There's nowhere to put the extra 10" (it's in the cab of the cc, the bed of the [current] ec). Unless the rear wheelwell in the bed is going to be practically on top of the bumper, that is..
 
edit: clarified a sentence (I hope)
 
PS- I seriously doubt GM is going to go to the trouble of yet another completely unique bed. To keep the wheelbase the same as the current trucks, the frame rails would be cut down and the bed itself would end up with the wheel openings located that extra 10" further back as I mention above. Keeping the bed the same allows them to use the exact same bed that goes on the crew, combined with the same cab that all usual EC trucks have, on a shorter frame. Wheel opening on either part would stay the same, but the wheelbase would shrink ~10". Probably going to check out the Chevy sight to see what it shows..

Edmunds is definitely wrong. Check out Chevy's web site for the specs (dimensions):
 
Wheelbases
Extended Cab Short Box / Extended Cab Regular Box / Extended Cab Long Box
134.0 / 143.5 / 157.5
 
Length
Extended Cab Short Box / Extended Cab Regular Box / Extended Cab Long Box
220.2 / 230.2 / 249.0
 
So, basically the wheelbase shrunk 9.5" and the length shrunk exactly 10".

Oh, and our "short box" is now being referred to as the "Standard Box".

Just checked the GMC site. Unfortunately it hasn't yet been updated to show anything about the EC w/short box yet. I assume GMC is getting this combo too? Maybe it's only Chevrolet.
