Filter needed a wash, and it needs to dry before oiling. So a little airflow from an exhaust fan, little heat from an AC exhaust.
And in less than an hour, a dry filter. Way better than just letting it sit for a day or two, especially in humid places.
Holy fuck you driving a semi?
Cold air intake for a half ton truck. Even car ones aren’t much smaller unless the engine compartment is tiny.
Better fuel efficiency, more power, more response.
Is this something I can/should put in my Tundra?
Personally I don’t like them. A lot of people like them though, They’re marketed to give you more horsepower/ mileage but actual testing suggests otherwise. They may be useful if your engine is highly modified but they also let more dirt through, especially if you don’t oil them properly. https://www.nicoclub.com/archives/kn-vs-oem-filter.html
Excellent analysis, thank you!
Up to you, I’ve done it to most of my vehicles, even if it’s just a washable filter without the cold air system.
Let me rephrase. In your opinion, what are the benefits of doing this that I should consider when making the decision whether to use one of these?
In theory it would pay for itself over time. You get better fuel economy, the filter is cleanable, so no got to replace.
The downside is, can be easier to hydrolock your engine in some cases.
Didn’t know you can wash air filters. Why are you gonna put oil on it?
Depends on the car/filter.
Many cars have air filters with paper in them. Cheap to make, cheap to replace. Do not wash!
It has to be a washable one. This cold air can have a washable cotton one, or a disposable paper.
The oil is the last layer to the filter. The mesh catches the big stuff, the cotton catches the finer stuff, and the oil catches the rest.
It goes on red (blue is another color) and when you can no longer see red, time to wash it. You wash it and it becomes white again.
I got about 50k km with this one, could have gone more, but just the time to do it. Million mile warranty on the filter too.
I even change my cabin air filters to washable, they even have Washable house ones too!
That’s amazing. I thought every car part is single use disposable nowadays.
Well you do need to throw the original airbox out to install this one!
They do make replace my filters for most vehicles, not just for cold air intakes.
