What's it for? by musicislife

Just under the hood of my I4, right in front of the engine is a plastic air ram. Part of it diverts the air to the exhaust manifold. After that is goes down in back of the radiator fans and under the battery. I couldn't reach any further under there to find out where it goes. In the part where it goes vertically, behind the radiator fans, it has turned up arms coming out of it that remind me of a Saguaro cactus. What are they for? Where does it go?

2008 Accord Sedan V6 high RPM on highway by marklud

I'm sure this has been mentioned before, but I cannot locate the forum. Has anyone else noticed how high the Rpms are at highway speed? At 60 mph my engine speed is well over 2000 RPM. Is this normal? I also have an 03 Honda pilot, and 60 mph is about 1600 RPM. Am I missing something, doing something wrong, or is this the way Honda geared the Accord? Right now I get about 22 MPG average, which I think is kind of low. My old 1991 Acura Legend, which I loved so much, got 25 mpg average! If I'm in the wrong category, please direct me, I'd like to get an answer. Thanks for everyone that contributes serious facts or opinions to this website, it is invaluable to any consumer!

Sounds like nothing is particularly wrong, but just how much is "well over" 2000 RPM?
 
Honda has geared the engine shorter (which means higher RPMs per MPH) so that it can more easily jump into VCM mode, using less fuel. If the gearing was taller, the engine wouldn't be able to stay in VCM mode as much, because it wouldn't have enough power at low RPMs to run in 3 or 4-cyl mode. Your Pilot doesn't have VCM, so it is always running 6 cylinders, so the lower RPMs make more sense in that application.
 
I know Honda uses this logic, because the Odyssey vans that have VCM run about 200-300 RPM higher at 60 MPH than those without VCM.
 
Regarding your old Legend...it was a smaller, slightly lighter vehicle about 60 fewer horses. It also is rated at 17/21 under today's standards (where your V6 Accord is rated 19/29) so I'm slightly skeptical that your driving style is the same. Not sure where the differences are. 22 MPG is the EPA estimated combined average for your vehicle, so you aren't far off from where you should be in your new car.
 
Best,

I noticed this too when compared to my previous 06 V6, which ran at about 1800 rpm at 60 mph. I figured to keep it in 3-cyl mode more often, which doesn't have nearly as much torque as full 6 cyl mode, Honda needed to keep the rpm's higher. I find I can run in 3-cyl mode up to about 67 mph. Any higher than that, it runs with 4 cyl. Driving around town 50/50 city/hwy, I can regularly go over 400 miles before fill-up. So far I'm averaging 24 mpg, less than 1 mpg difference from my 06 V6.

Will the new 2009 Acura TL wheels fit the new 2008 Honda Accord EXL V6 sedan? They are 17x8 I believe.

A quick look tirerack.com shows various mfg's rims 17 x 7.5 & 17 x 8 as qualified substitutes.

how do you know when you are in 3-cyl mode or 4-cyl mode? i know that the eco light is on in this mode. my 09 accord coupe w/ the v6 auto "chug's" at 65mph like it is hunting for a gear with the eco light on.

2008 TSX A Spec wheels by jeremyaaron

I just ordered a set of 2008 Acura TSX A Spec wheels with center caps, and Honda TPMS sensors. I have a 2008 EXL V6 Sedan. The current wheels on mine are 17x7.5 with a 55 offset. The A Spec wheels are the same 17x7.5 with the offset of 55. These will fit my car correct with no issues?

Yes, they should work fine. I assume you are switching the same tires from the Honda wheels to the Acura wheels, or are you changing tires also?
