Cold Air Intakes. Debunking false claims.

How did you see the particulate blow through a new K&N?
What motor runs a .00030 piston to wall clearance?

 

I took out the filter during a service on a 700 grizzly and saw dirt stuck in the filter oil on the throttle body side, I've seen it on a handful of Polaris' too. One too many zeros. Should be .0030. My bad.

 

Dirt stuck in the filter means the filter worked right?

 

Yes. it wasnt in the filter, it was lining the intake, and not the only time I've seen it with this type of filter.
Some people use them without issue, and that's great. I personally don't care for them.

 

When you say only capable of inhaling, what exactly does this mean. Stock form? It's hard to believe the way your wording that its only ever capable of 425cfm. That simply can't be true.

 

I don't see any dirt from using these K&N filters

 

I think what many people forget is, it's not about how much air will physically flow through the filter, it's about how much air the engine control unit demands. There is an optimal ratio of fuel/air mixture and that changes depending on what the vehicle is doing. Accelerating, towing, cruising, etc. So no matter how much air the filter will flow, it is useless above a certain point because the computer will just limit it. Whatever that max is, the stock filter is obviously adequate.

 

Those tests were done in a controlled environment. Seen real world test results n yes the s&b is one of the better cai set ups wix replacement was much worse. Cat has a list of stock replacement filter tests done in extreme real world. Wix filters failed. They didn't test k&n tests were done in a gravel pit in mt, a coal pit somewhere in China and a IRON pit in mn.

 

OEM paper filter in the OEM intake is the best for performance and power on the Tacoma. the rest is misrepresentations about how more air into the engine will produce more power, performance and MPGs, remember this is a pickup truck, not a street Rod. People are watching too much of Gas Monkey Garage and Street Outlaws on Discovery channel.

 

Can you please post the link to the test that was conducted? Of course the tests were conducted in a controlled environment otherwise it wouldn't be a good test. You have to isolate the variable you are testing which ISO 5011 does. That test also uses a standardized dust A4 coarse dust which has a variety of sized particles in it.

 

I think that there may be some misconceptions about intakes. Its not going to allow more air into the engine because the engine is going to suck in all the air it needs, thats what they do since the a basically a big air pump. The most a aftermarket intake will do for a engine is pull in more cold air if the stock intake does not do that and make it easier for the engine to suck the air in. The easier it is for the engine to suck the air in the more efficient the engine becomes. In the case of my Tacoma with the S&B intake the effort needed to pull the air through the filter and into the combustion chamber is less with the aftermarket than with the stock intake.

 

Wrong, the OEM intake pulls cold air in thru the outside fender well and filters(OEM 3 layer air filter) it effectively to the engine, the K&N CAI pulls hot air because its filter remains inside the engine bay and doesn't filter it as well because of the construction of its gauze material cone, not outside cool air. is used in the K&N CAI.

 

I never mentioned K&N and yes the stock intake is a CAI. My personal opinion is that the K&N intake for the Tacoma is garbage but not all aftermarket intakes are built the same.

 

It baffles me on how long this thread is. It also baffles me that people who have no idea what they are talking about are just puking up bad information.

This debate has been going on with every car forum since the beginning of car forums.
Take a look at the engines that make power over stock: They all have modified intakes and filters.
These manufactures do not spend hundreds of thousands of dollars on R&D to "not make any more power". This stuff is a not a gigantic conspiracy.
A high performance racing type filter is not designed to filter the same as a stock filter. Never has been and probably never will be.
If quality filtration is your goal, than the majority of intake kits are not for you.

Bottom line: A proper aftermarket intake will allow you to make more power than stock. This is not an opinion, but a fact proven time and time again.

 

I think the real question is power per dollar spent.

 

Op when does the debunking begin? When are you heading to the dyno?

 

Dyno runs this Saturday @9am. Going to document everything and make a youtube video.

 

Standing by

 

If anyone is in the area and wants to come watch for fun, here is the shop info. Ill be there at 9am
