I just made a DIY icebox this weekend and I need to switch out my stock filter. I did countless of searches and I found two choices that I want to go with. Its between the K&N RU-2820 & the RU-3130. The RU 2820 is bigger while the 3130 is tapered off. Which one would you go with? Some say the tapered one is better b/c of the extra space in the airbox allowing air to flow around more freely. And others say the 2820 is better b/c its more fatty. I don't know which is true. Any input? Thanks in advanced for your time.

I just did the 3130 today on my stock airbox...It was only $20 ordered from Autozone...I didn't feel a difference btween this one and the stock one...I didn't even notice a sound difference unless the top box is off...

 

Use the 2820, you can make it fit 100% like a stock filter does.

I didn't do it for power, I did it for longetivity. I'm still on the same filter that I was using 90K miles ago.

 

I personally prefer the RU-2820. It is the closest in size to the stock filter. You can attached the white plastic piece (see PatrickGSR94 pictures) which supports the end of the filter). And it has a built-in velocity stack, which aids in smoother airflow into intake tube.

The RU-3130 has a little less surface area than the RU-2820, because of the smaller size.

 

yup yup I used Bret's how-to to make mine wayyyy back in the day in 2001.

whoa damn Bret, your post count (1666)

 

Back from the dead, but how did you remove the white glue from the stock filter?
Clean job...

 

Does anybody have a current write-up of how to fit the RU-2820? All links and prior pictures are all dead.


Thanks
