Hey all...ive been reading that K & N air filters could be the cause of pinging and other problems because of the residue that comes off these filters. So i just wanted to get an idea if this is true and i thought the best way was to see how many of you a.) have a K & N and are pinging b.) have a K & N and arent pinging c.)dont have a K & N and are pinging d.) dont have a K & N and arent pinging....you can just post the letter answer if youd like and ill post the results soon as i get enough people to respond-if the K & N comes up to be affiliated with the pinging in more cases than not, you can bet that ill toss it in a heartbeat. thanks for yalls time
I don’t think you can conclusively conclude that using a K&N filter and pinging are directly related. Pinging has many origins, and although there is talk of dirty MAFs causing pinging, I’m not sure it’s 100% proven. It’s also not a given that a properly oiled and maintained filter of this type will even give off the contaminants you mention -- but it is certainly more possible than with a paper filter.
IMO, these filters are made for racing. The average Joe gains little (if any) advantage in HP or gas mileage, at the risk of allowing more dirt into the engine, which is (to me) not worth the risk of owning one and the ultimate reason for giving it the heave-ho. Remember, race engines are rebuilt often, sometimes after every race. What do they care about accelerated wear?
If you're going to toss it, toss it for this reason -- not the loosely connected pinging issue.
Mickey,
I agree with you totally. However, i know this is not a 100% error proof scientific experiment...it never was intedended to be one. I would just like to know if say...85% of people with K & N filters have pinging problems and 20% of people without K & N filters havent heard their truck ever make the slightest ping... then something like that should ring a bell and i would take off the K & N just to see if the pinging clears up any. I guess i am desperate for a solution and willing to try anything...everything else that ive tried has no effect.
My 95 Thunderbird will start pinging once in a while (around 15k miles or so) and I just clean the MAF and it's good again.
K&N filters are more likely to dirty the MAF because of over oiling. I wouldn't use K&N for a million dollars because a friend of mine ruined an engine because of a bad filter with a hole in it. Worked in a dusty environment and locked the engine up.
d) I don't use a K & N filter and I don't have any pinging.
I've actually thought about using a K & N filter because the air intake on my Taurus is quite wimpy by design. I'd really like to get more air flowing into the motor and I heard the K & N allows for that.
But for me, the drawbacks of the K & N filter (allowing more dirt in, MAF issues) are enough to outweigh any possible benefits.
That's just my own opinion, I know others may differ.
Hey bass,
I gotta fo with Rock here. I personally don't have a K+N. I wouldn't use one either due to the oil residue, dirt filtration, and other issues. As far as the pinging, there are multiple causes for this, just read the other threads. And remember a company is only going to tell you what it takes to sell products. There are several companies on the rise, thanks to this issue, making the round paper disposable filters. I will post links later. It is bedtime now. Good night all.
....although there is talk of dirty MAFs causing pinging, I’m not sure it’s 100% proven.
I think that Ford has grudgingly conceded that there are cases where a direct correlation can be shown between pinging and a dirty MAF. Read here: Connection B/T Dirty MAF and Pinging
"Quietly" might be better choice, since it via the TSB route and not generally available to the public -- unless you want to pay ALLDATA or have friends on FTE (thanks, Ken!).
As for your point, you're correct. "100% proven" was a poor choice of words and didn't relay what I was trying to say. I kinda meant "not the most likely cause of pinging", since I think carbon build-up is more common and likely to be the cause in these engines, especially those with higher mileage. But I admit that I don't have enough evidence to back that up, and could be quite wrong.
Bass,
I still think your poll is flawed and not likely to offer any good data, as it's simply too uncontrolled and subject to too many variables. Instead, just do this: Leave your K&N on and clean the MAF. If the pinging goes away, then you had a dirty MAF and may want to consider chucking the K&N. If it doesn't go away, then it sure as heck is due to something else -- not the filter or MAF. Simple.

Rock,

Actually Mike, it's funny you mention that....I do not subscribe to ALLDATA and although Ken is a great source of info, I did not rely on him for the MAF TSB. Your going to cringe when I tell you this, but I honestly found it on the internet! I often visit a variety of truck and car-related websites and there are people posting TSBs and other great tech info all over the place. That it (the TSB) is now public knowledge (albeit still somewhat undiscovered) should really not surprise anyone since it is important information to know for any Ford truck owner.
