I've had intakes on every car I've had. I had a CTS for 11 years, no issue. K&N and all the intake companies wouldn't be in business if it was a product that destroys your car. Is there really going to be a huge problem on oiled filters on this car? Even with a paper filter it's never like even gray after a year going, so not all that much material is even trapped in that, and I clean my oil liter every oil change and once mid-winter and twice during the tree pollination period. I have a Mishimoto myself, but you guys might only know K&N.

I was in a thread on another site and every poster said they're awful, however I never had a downside to any nor has a garage ever blamed it for anything going wrong.

Short answer yes, they can actually loose power, heres why:

K&N drop in filter for 2.0T results/comments

Recently purchased a K&N drop in filter for my 2008 Gti and did some logs. At first it felt like it had more power and then I did some logs What I found was that over most of the rev range the K&N produced less flow than the std air filter. Where i use to get between 197gs to 200gs peaks I...

I have a full intake though, not a drop in. These compare drop ins to drop ins.

Afaik they use the same material on all their intake filter, drop in or not. At any rate if your cleaning it as often as you are should not have a problem anyways. Most people don't clean them that often.

K&N offer the best performance period.

K&N offer the best performance period.

Thanks for helping me prove my point even further! The video proves how many more particles the K&N lets through. It was far and away the worst filter in terms of actually filtering particles from entering the engine. Another point in the video he even states that he thinks the extra air cleared out the filter before the test. As time goes on and the K&N collects more they actually will flow less than stock. But again op cleans his frequently so.... The largest gains should be coming from the intake tubing removing restrictions, if any, from the factory intake boxes. Not the filter.

 

[qman]

Yes it is quite obvious that if you let in more air you get more particles with it. That is simple logic.

The question becomes "does it matter?"

With regular ole paper filters you are also letting in particles. Just not as many. Does it matter? And if you answer yes, can you quantify your answer?

 

[NoEgo]

This video persuaded me to quit the K&N oiled filters, but that's just me.

K&N offer the best performance period.

The real question is: does the stock filter choke the engine? If the answer to that is no then the higher flow of the K&N is meaningless.

I've never experienced issues with an aftermarket intake. Just stick with the dry filters, and get a back up filter for the times you need to clean the filter. While aftermarket CAI/SRI don't require any sort of tune, I think a minor tune would be beneficial in optimizing an aftermarket intakes functionality.

 

[GoLowDrew]

No plan to debate with anyone on flow or power. But rather to reply back to the OP.

I've had 4 cars with K&N going back 30 years. Two were Honda J35V6. On K&N from new to 80K and 65K before I sold the cars. One Civic from new for 110K before I sold it. All three were drop in filter in OEM air box. And one Nissan 210K miles on CAI, later sold the car. All of them had no issues.

Yes, I read the replies with people who had issues. And not trying to debate that.

I just follow the guideline of if you think you add the right amount of oil, that's too much.

I will say it was nice not spending any $$$ on air filters.

Do I run K&N now? No. Why? Because I give away my cleaning kit and oil to when I sold the last car (with K&N.) There is a cost with the initial investment. I don't mod cars like I used to. Getting old. So that's why I'm not using K&N. Would I buy it again? Yes. Will I? No, again, because I don't mod anymore.

 

[NoEgo]

The real question is: does the stock filter choke the engine? If the answer to that is no then the higher flow of the K&N is meaningless.

Plus, the K&N oiling process is wholly imprecise with the MAF sensor only inches away from the filter and any excess 'oil' residue that comes off of the filter as the unsuspecting driver goes merrily down the road, and later seeing a 'check engine light' on the dash.

Exactly. To me, and it's just a personal feeling, the very very slight chance of a 1-5 hp increase by using a K&N (an increase which will not be meaningful or noticeable except on the very inaccurate butt dyno) is not work the risk. I replace my air filters with OEM every 1-2 years as needed. The cost is minimal compared to costs of fuel, insurance, tires, oil changes, brakes, depreciation etc..

I've seen cars run on ebay filters for years uncleaned, stock filters probably from the factory because the owner didn't know any better or care, and a host of other aftermarket filters. This is not going to be the failure point of your engine in terms of particles. Love your clickbait questions though, when the teacher told you there were no stupid questions, you took that to heart.

 

[enne]

The gains are so negligible that I don't even see a point in using them, but they're not going to break your engine.

 

[qman]

I agree with most of you. Who gives a rats? In 1997 I bought a K&N for my 1994 Suburban and I still have it. I've probably saved a zillion bucks on filters over the last 24 years and 150,000 miles. My current 2005 Accord came with one so its still in there. Gonna save a zillion bucks on it too.

But you know what? I'm also gonna save a zillion bucks on my other cars cuz I'm just gonna do like my neighbor does with his 1972 Chevy Van. He takes the filter out, bangs it on the ground, and puts it back LOL. He's been doing that since he bought the van in 1972. Although I'm sure he's replaced the filter at least a couple of times.

This is one of those purely opinionated discussions without any real scientific data like oil. Has anyone ever heard of an engine failing due to a K&N filter? Has anyone ever heard of an engine failing due to not using synthetic oil? No and no.

. . .

All depends on the car I spoke with rv6 performance and an aftermarket intake on an Accord actually decreases power due to maf sensor being thrown off but with custom dyno tune or etune there’s horsepower to be made following an intake. Varies from car to car. Chances are a stock air filter chokes any average car since they’re focused more on filtration not air flow. A k&n air filter in stock location shouldn’t need a tune because you’re not moving the maf sensor around.

If you regularly maintain your car and use the OEM style paper air filter it'll last over 200,000 miles. Why would you want to mess with that?
