I know there are many choices of air filters to choose from nowadays but I just wanted to see what everyone was running. What air filter are you using and why?

I am using the Green Filter just because I have never used one (always K&N or AEM) and I have heard good things about it. One thing I have noticed, it is about half the thickness of the stock paper filter.

If anyone is running the COBB filter, is it also about half thickness of the stock one?

I already made my purchase but I was just curious what else was out there and why people think they are good options.

I have the cobb filter and yes it's a lot thinner than stock. I think it's exactly the same size and mesh design as the green filter

The Cobb drop-in and the Green Filter drop-in are exactly the same, Green Filter makes them private label for Cobbs. I love my Green Filter and I have had awesome gains with it, saves the hassle of messing with the intake and because of the enclosed airbox, less cleaning at the trade off of maybe 1-2 WHP

I am a believer when it comes to the AEM Dryflow filters. Flows just as good as the oiled filters but no oil. Also SUPER easy to clean

 

[aar0nsky]

Do they offer these as a drop in for our cars?

No, they are all conical filters and come in any/every size you could want. It will not fit the stock airbox though. You can do modifications to remove the air box and make it fit.

Ah thought so. Yeah maybe once I am out of warranty and I put on my custom CAI I will most likely order an AEM dry flow.

An intake will not do anything to your warranty. If you have the car with full exhaust and intake and tune and something breaks, you still have a warranty. Nothing can legally VOID your warranty. If something does break, they need to prove that it was the modification that caused the breakage. Even if you cook a turbo and they, for whatever reason, could prove that the intake caused it, you will still have a full warranty. Your warranty claim for the turbo would just get denied and you would have to pay for it.

I would imagine that Ford is going to be easy going with the FiST and FoST because they also have the most modified car on the planet in their lineup, the Mustang.

As much as I appreciate the advice, I cannot just take your word for it. I have read horror stories about modifications and the saying that it depends on the dealer seems to come up alot. I cannot afford to take a chance so unless I have it in writing that mods will not void my warranty I am going to play it safe.

I have worked for a large company doing warranty for a long time. I will not say who it is, but most people on this forum will know of them.

This is the reason I write about it. People are typically misinformed. It helps to know how it works because it is better to go into the dealer informed rather than misinformed.

The dealer actually has nothing to do with the warranty procedure. Basically if something comes in, it is documented and it is submitted to head office. It is Ford of America/Canada who decides whether they cover it or not.

In my experience, dealers are on the customers side because they want the repeat business. A lot of times if a warranty claim is denied, the dealer will try to work out a deal with the customer or even cover costs to save face.

 

[aar0nsky]

Yeah if they told me it wasnt covered I would most likely do the work myself anyway. I hate dealing with dealerships as it is.

Yep, this. It's the Magnuson-Moss Warranty Act - it's a Federal law. The short version is that you can't be denied a warranty claim simply because you used aftermarket parts; the manufacturer would have to PROVE that the design of the parts OR an improper installation of the parts caused damage. You can read it here, direct from the FTC:

I've worked in several dealerships, and this is my go-to info for customers with similar concerns, even to this day.

One thing to note, though. Tampering with factory installed emissions components is a crime.
Warranty is one thing, the law is another. Will you go to jail for removing your catalytic converter? If you REALLY earn the attention of Mr. Lawman, who knows? Use your best judgement, and a bit of common sense, and you should be fine.

Also, get to know your dealer. Ask your salesman who the Performance Specialist (read: resident gearhead) in the dealership is. In my case, the Fixed Operations Manager at my old dealer. He drives some seriously modified vehicles. Most are SVT's, and and most of those are 475hp or better. He has provided me with some of the best advice concerning mods vs. warranties, and has even asked me what my plans are for most of my last 10 or so cars, dating back to when he was "just a wrench." In other words, he gets it.

If the dealership you frequent has a Service Writer or Manager similar to mine, they will often provide the best insight to your dilemma.

I think the issue is that people hear down the grape vine that "Bobbys warranty got denied when he blew his motor. Any modification VOIDS your warranty!!" but they don't understand that even if a warranty claim is denied, you still have a perfectly intact warranty.

It is just the way that information passes from person to person where the real story gets lost.

 

[cruster]

Yep, it's like a bad game of Telephone. Things like Mitsubishi and Subaru cancelling warranties wholesale on Evos and WRXs because they were "raced", or used in a way that the manufacturers could argue represented a violation of the warranty agreement, dilute the issue, too - that stuff takes on a life of its own. And, ultimately, the warranty is an agreement of sorts, so the purchasor has some obligations in order to keep it viable - but those are usually limited to maintenance and common sense. You have to change the oil to keep up your end of the bargain - but they can't tell you what filter or specific brand of oil to use.

Car forums and Magnuson-Moss are always fun, someone's always running down the halls. waving that flag. The reality is YES you have to be concerned, because if they deny the engine warranty because you have custom lug nuts then it's up to the lawyers to sort it out and in the meantime your car's not fixed or you paid for it out of pocket. You have $5k sitting to tie up that way, and gamble that if you lose you have another chunk of change to pay the lawyers?

So yes it's a concern.

Where did u find aem or dry filters

 

[Vixenlotus]

I am sticking with Stock. In the past i have always used a K&N but they let a great deal more dirt into the motor. Sure the K&N and Green flow a bit better but at the cost of poor filtering. I plan on keeping my fiesta for a long long time and want to keep as much dirt as i can out of the motor.
picking up an extra 2 hp as the cost of letting dirt in is not worth it for me.
I would say if you are going to keep the car for under 100k or so miles do what you want. if you want to keep it for the long hall use a stock one.

After 100k I will probably like to go with a big turbo. Probably different internals.

Hopefully by the time I hit 100k mi theres a better hothatch out...
