The filter location is behind the glovebox. To remove the glovebox door, you need to squeeze the upper rear corners inward & the door will come forward & lift completely off. There is a realease tab on the right side of the filter access door. Open that up & remove the dirty filter. If it was like mine, it will be packed full of debris. Wipe out remianing dirt & reinstall everything in reverse. I changed mine after having it at the dealer for low A/C output & dust coming out ot the vents when first turning it on. The dealer said all was fine, which of coarse was not.

Same thing with MKX. It will let you build & price, but those items don't come up.

I don't have these wheels, but probably wouldn't notice the noise, since I never drive with the windows open & always have the radio on. Perhaps, this is why so few complaints?

There have got to be some pretty crappy dealers out there if they can't follow up on something as small as this. Things like this are how I judge a dealship. It may be only a 1 dollar item, but it sort of sets the tone for everything else in the future at that dealership. If you are talking to a salesman, I'd go the manager/owner of the dealership & let them know how I feel. They don't want & can't afford negative publicity right now, so they should bend over backwards to get this taken care of.

Here is one article on tuning that suggests that if the engine is stock, the factory setting is the best overall. Tune Into This - Engine Tuning 101 AFR, MAP, IAT... Confused? Not Anymore all contributors: Ryan McKay Good tuning is the key to unlocking the potential of any engine. OE manufacturers spend ungodly amounts of time, money and research fine-tuning engines to run as efficiently as possible at all times, under any conceivable operational conditions. Simply put, if your engine is stock, it's unlikely you can get a better overall tune than the one it came with. Make a few changes though and things can change rather quickly. An internal combustion engine is basically like a big air pump. As it comes equipped from the factory, it will flow a set amount of air based on things like engine speed, load, etc and is tuned accordingly. When changes are made to the things that regulate the amount of air that gets into an engine (cams, header, intake, forced-induction, etc.), changes need to be made to the engine management to compensate. This entails adjusting fuel and/or ignition timing, at minimum if the engine's potential is to be realized. Basically, when airflow is increased, fuel delivery must be increased accordingly. The goal is to get the fuel and the air into the engine in the correct ratios. But don't be fooled into thinking that tweaking the air/fuel ratio (AFR) is the only thing that needs to be addressed when making serious changes--it's not that simple. Getting more air and fuel into the engine means that there is a bigger explosion happing, which means higher temps and pressures in the combustion chamber, which can dramatically increase the chance of detonation and engine damage. As such, ignition timing often must be adjusted as well. While comprehensive tuning involves more than just tuning the fuel delivery and ignition timing, they are 90 percent of the equation. Also, if these two things are in order and set conservatively, chances of engine survival are good. Just like everything in life, tuning is about compromises. The key to getting the best tune is to balance maximum power and engine safety, without running the car on the threshold of destruction. Twenty years ago, tuners relied primarily on their eyes, ears, noses and timeslips to tune, which required years of experience. Today, thanks to modern fuel injection systems, we have a mess of sensors under the hood, which makes things a lot easier. - Check out the following pages for more engine tuning info!

Since they are suggesting it could be fuel related, you may want to try another station or brand to see if any change.

I used to subscribe to a truck magazine. An article I read about engine mods stated that many of them do improve performance. However, they also make the engine work harder & will likely shorten its life.

Thanks for clarifying that. I also follow the maintenance schedule & have never had engine problems on any car I've owned.

My advice is to save your money. When I bought my Lightning, the dealer tried to sell me all the way out the door & even offered to rewrite the contract at a lower interest rate if I took the warranty. That made things crystal clear. In the 10 years & 190,000 miles I owned it, I don't think I spent $2000.00 in repairs on it. Five years later, I still see it around town on occassion.

I was under the impression that the oil that comes in the engine when new is supposed to stay through the breakin period?

Is this pretty much plug & play or will the THX need a mod to use it?

Give Crutchfield a try. They offer a lot of advice to make a good choice. http://www.crutchfield.com

I replaced my cabin air filter $24 & the air flow is somewhat better. It still sends a fair amount of dust out the center vents when it starts up. I got the filter from my dealer. They had to order it. Parts America lists it Motorcraft HP65, but they don't have them.

I agree with you there. All of the cars I see at the dealers that have the protective film removed from the nav screen are covered with fingerprints. Touch screen technology seems to be growing though. Many of the higher end computers are trying to do away with the keyboard are are going touch screen. Same with iPods & cellphones.

The price for Sirius was just for the tuner & to install it. No service at all. I factory ordered my car because at the time, I thought I didn't want nav & they couldn't find one with everything else I wanted. I forgot to ask for Sirius & by the time I woke up, the car was on its way to being shipped. I have a feeling that the Audiovox units should be fine. The company has been in business a long time.

I just checked & mine were actually $1695.00 installed. They play individual or same on both.Plus, it has jacks to add games. The best thing about them is that the headrest is adjustable foeward & back. Some don't like the headrests that lean way forward. I think the lower price is because of X plan. I forgot to ask for Sirius when I ordered mine & as you can see, I paid way too much for that as a dealer add on. The Head Rest DVD is $1,695 installed Sirus Radio $495 installed Spring lowering kit $795 installed Tint $150 installed

If your spending that much, You might just as well have bought the Invision that the dealer installs. They cost me $1595.00 installed.

I bought one from them & it looks good & the fit is also very good.

Try Magnaflow. They have 2 listings for the Edge/MKX. One states dual rear exit & the other dual split rear exit.

A big company like Gibson putting stuff like this on the market doesn't say much for them. How do they know if their products work/fit the application if they don't actually install one?

OK, I read the owners manual. That screen shows average speed.

No, there is another screen that I THINK says average mpg. That number doesn't seem to add up to me either.

I think mine shows 37.

I leave it on miles to empty. Once in a while, I check to see the MPG. Currently shows 22.1. Highest ever is 22.3.

I've read articles that strongly advise agains't using Armour All. I use Mothers Protectent. The Mothers leaves a very low sheen instead of the blinding glare that Armour All leaves.
