I don't know and I don't care. I never purchased any of these brands.

No. They work. I have them on 2 of my 3 Buicks. The 3rd is still the 2bbl Rochester. I have the filter for the 4bbl carb and intake system I am going to swap in.

You can even get a cold air pack with K&N style filter for a Prius. Adds 10 hp. If you look at how restrictive most modern intake systems are, eliminating a lot of that can allow the motor to produce more power.

My Stage 1 has a 14"x6" tall filter on it. My 350 has a 13.5"x4" on it.

When the '70 Stage 1 engine was rated at 360hp, it was through the restrictive intake. Carb and just the air filter base plate it was @425.

For most people, it won't matter. But even over the lifetime of the car/truck, you will save on filters.

Fram even tried to market their own under the Air Hogg name. I have a bunch of them new in boxes that I got for about the cost of a regular Fram while the Air Hoggs were being closed out. Only issue is the plastic/rubber end pieces are Fram orange.

That was helpful.


Is K & N the Monster Cable of the auto industry?

No, it is not.

Though it would be helpful if you bothered to post a few of your concerns.

The value of K&N's, and any oil-based filtration is hotly debated.

Many people, such as myself have used their air filters for tens of thousands of miles with no ill effects. They do demonstrably (see what I did there?) increase air flow into an ICE. This is great for some fuel injection systems, as they will increase gas flow to maintain a proper air:fuel.

Not necessarily great for carbureted systems, as one has to then make internal adjustments to compensate for the leaner air:fuel, if it impairs performance, or to maximize it.

The debate arises as many don't believe it filters particulate adequately. Many testimonials agree airflow is increased but that engine wear is also increased do to poorer filtration compared to conventional filter media. Others, such as myself, have not experienced any measurable wear that could be attributed solely to the K&N media.

I stopped using them in my bikes and and cars years ago only because I got tired of the cleaning and oiling process. Too much oil, even after draining the excess, the cars and bikes would smoke a little until the real excess was burned off. Eventually they have to be cleaned and re-oiled. I got old and tired of that.

There have been controlled studies and testimonials that seem to support both sides of the equation. If you have any doubts, don't do K&N.

I am that Masked Man.

All you can do, is all you can do.

There’s trouble — it's time to play the sound of my people.

Your boos mean nothing to me, I've seen what you cheer for.

Insisting on your rights without acknowledging your responsibilities isn’t freedom, it’s adolescence.

I've been to the edge of the map, and there be monsters.

We are a government of laws, not men.

Everybody counts or nobody counts.

When a good man is hurt,
all who would be called good
must suffer with him.

You and I have memories longer than the road that stretches out ahead.

There is no safety for honest men except
by believing all possible evil of evil men.

We don’t do focus groups. They just ensure that you don’t offend anyone, and produce bland inoffensive products. —Sir Jonathan Ive

An armed society is a polite society.
And hope is a lousy defense.

You make me pull, I'll put you down.

I *love* SIGs. It's Glocks I hate.

"Though it would be helpful if you bothered to post a few of your concerns."

Mainly money.

I know. I did not mean to be [insert your choice word here]

I don't know why I posted that... had nothing better to do at the time I guess.

well Dennis, I've been using the same one since 1997, so 32 years worth of air filters I didn't buy.............

And the Air Hoggs I got on clearance were about $6 each, with a $4 rebate for buying a Fram air filter.......

Saint Cloud, Minnesota, where the weather is wonderful even when it isn't.

Well, I've had the motor in my '69 since 1997. It originally was built for my '72 Skylark. I transplanted it into my '69 GS 350 spring break 1998.

My joke with my ex-wife was 2 of my 4 cars were older than her. My friends knew they would also outlast her, but never told me that tiny useful fact.

I wish I could do that, but I'm not built to do the proper maintenance.

Not really. imho, that moniker would be better suited for BG Services or Chemical Guys.

The maintenance routine Ram mentioned, with potential side effect than can harm an emissions test or sensors if too oily is the main reason modern daily drivers don’t benefit from them. (The MAP sensor can adjust air/fuel if a little wrong.) But for a classic car you’ll keep or certainly a race car, it’s a solid accessory to own.

Not only does it make air move faster, it makes clocks move about 45% faster too.

Engineering Explained did a video on the subject of aftermarket air cleaners and found that they did indeed make a difference. Not a huge difference, but it was measurable.

D'0h, I meant 87, not 97.

A K&N air filter is one of the first thing I put on my motorcycle when I buy one. A new air filter for my bike is around $50. I buy 1 K&N filter and never have to buy another filter until I buy another bike. So far 7 years and 100,000 miles on 1 air filter.
