Cleaned the RB REVi Intake Filter
Over winter break I decided to clean my RB intake for the first time in the 2 years I've had it on. And man am I glad I did. I first took off the accordion intake tube, and the blue aluminum tube with the MAF, then removed the filter from the box. The filter element was caked with tons of dirt, but the air box itself wasn't too bad, just little piles of sand. Here's what the filter and box looked like:
I found that a toothbrush and a flexible plastic fork works wonders to get most of the loose dirt out without damaging the filter. The toothbrush gets the outside edges of the pleats well and the fork gets in between. The vibration of the fork as it scrapes the sides REALLY helps shake out a lot of the dirt. Here was the amount I was able to get out:
After that I doused the filter with K&N filter cleaner solution, and let sit for 10 minutes per the instructions. I then rinsed the filter by sticking the head of my garden hose inside and using a moderate flow of water. Wow it is now so much cleaner:
While letting the filter dry, I vacuumed the inside of the box. You can also use this time to clean your MAF with MAF cleaner. After the filter was mostly dry I sprayed a good coat of K&N filter oil, then reassembled everything.
Driving the car I immediately felt better throttle response, especially at mid-high rpms. This is definitely worth doing if you haven't cleaned your RB intake in a while!

^^what he said. if you keep having such bad routine maintenance behaviors, you can kiss your motor bye bye to an early grave. knock on wood it don't.
but yeah...performance air filters have the performance because... well, its a thinner filter. so clean more often. and clean at least once a year.

ya i'll be cleaning more regularly from now on... I hope there's not much that went through the filter. I think it should be fine though, seeing that the inside of the filter was perfectly clean. It did surprise me how much dirt can get lodged on the outside though!

I zoom therefore I am.
For over oiling: http://www.knfilters.com/filter_facts.htm#OILING
When servicing a K&N filter, take care not to over-oil the element. Besides impeding air flow, excess oil can migrate into the intake system where it can coat electronic sensors, which some OEM’s claim may hinder the sensors’ operation and result in a repair that will not be covered under warranty. Although K&N disagrees with such claims, as explained in more detail on this web site, in order to avoid a dispute with an OEM over the denial of a warranty claim, we suggest that you be careful not to over-oil your K&N air filter. Never saturate the filter. If oil drips from the filter, wash it and start over. Use only K&N oil. For example, an E-1500 filter has 92.4-inches of surface area requiring 1.707 fluid ounces of oil. Follow oiling instructions included with your filter or refer to the instructions listed here.
-----------------------------------------------------------------------------------------------------
K&N's suggested cleaning interval for filters (non specific instructions)
http://www.knfilters.com/filtercharger.htm
we recommend cleaning your air filter every 50,000 miles. To clean and re-oil, purchase our filter Recharger® service kit and follow the easy instructions
Of course, if you read the PDF from http://www.kandn.com/instructions/69-6030-1.pdf
it states:
K&N suggests checking the Air filter element periodically for
excessive dirt build-up. When the element becomes covered in
dirt (or once a year), service it according to the instructions on
the Recharger service kit, part number 99-5000 or 99-5050.
excessive dirt build-up. When the element becomes covered in

So saying he's fine at 25k because they recommend re-oiling at 50k isn't really correct. He went 2 years without checking and they suggest every year.
