RPO K47 Air Cleaner, High Capacity

[364cubes]

Anyone have an idea what changes when you order the RPO K-47? Is it just a different filter or does it change the housing?

My understanding is that it's just a different media that fits in the same housing. I have already bought a replacement filter for my '06 Sierra, and the book said it fit either one. The filter I bought is the high capacity one.

It the same media as the standard filter, it just has more pleats per inch (more surface area).

If the filter with RPO K-47 has more pleats will it have more restriction?

 

Restriction = loss of power which I don't like!!!

I have not personally done any tests but I would not imagine any more restrictions with more pleats. In fact perhaps just the opposite. There's more surface area for the air to go through than the standard filter.

 

Just my 2 cents.

I just got back from the auto store. Picked up a WIX air filter and they asked if I needed the heavy duty or light duty model filter. If you sit the filters on the counter the heavy duty stands about 1/4 of an inch taller....more surface area. My truck came with the high capacity filter and at $2 more I had no reason not to get the HD filter.

Can you give us the WIX HD filter P/N? Did you buy it at a NAPA?

 

Thanks,
