Automobile Engine Air Filters

No dude...I am advocating for purchasing high performance engine air filters because they make your car go slightly faster.

I edited to take out that part. Thanks for your candor

So what brand should I have gone with?

Does K&N suck? Damn....

Hey man I appreciate it for learning me on this topic

What diameter and using what? Pause

Nothing screws up an IAT Sensor faster than over oiling the filter pleats with the supplied oil.
Use very sparingly.

Yep, it sticks to the filter and ends up the sensor.

I don't think you could feel a performance increase, if there would be any

Only increases I noticed was the noise level under the hood and the increase of silicates in the oil analysis.

My Tundra has no noticeable difference in performance despite the expensive air filter. PIA to clean IMO. Would rather just replace the filter with a cheaper one when needed.

But good on you for wanting to do your own maintenance and improving vehicle performance. Just not my thing.

There was some debris blocking the air flow underneath the filter.

Gotta question the air filter system if there is debris that made it past.

Stay with a paper filter. Cheaper and what your car was designed for.

Which brand is better for my future reference? Second time asking. Would appreciate a response

Whatever OEM filter your vehicle calls for. But Puralator makes a good aftermarket filter for both oil filters and air filters.

Edit: since it seems like you are generally curious, anytime an aftermarket product is sold that is telling you it will gown you “X” horsepower, “x” extra MPG, etc they are full of shite.

If you could slap on a $70 filter or a $100 throttle body spacer and gain horsepower and MPG then it would have been done by the manufacturer because they are trying to squeeze as many HP and MPG as they can out of the smallest engine possible so they can keep up with the CAFE standards.
