I recently needed to change my air filter, and was dismayed about the price, for one simple panel filter, it was going to cost me over £9! I decided this was too much for a simple piece of corrugated paper. I set about finding an alternative, including using aftermarket parts. I didn't want to fit some cheap and nasty filter to my car, but the price the main dealer wanted was a little too high. I priced up other options, like an air filter that could be re-used. After going through many websites, I liked the idea of a simple panel filter, which could be cleaned, oiled, then re-used many times.
The idea sounded fine, so I priced up the equipment, this consisted of the Pipercross panel filter itself, a bottle of oil to trap the dirt, and some cleaning solution. I was surprised at the result, it was going to be very expensive to start with, but it would save me money in the long run. I had looked at filters by K&N and other companies, but had set my mind on one by Pipercross.
In the end, I happened to be in my local motorist shop, and saw everything I needed in one bag, this was on offer at just £36 ($57.78) which was co-incidentally the same price as the Pipercross website. The kit contained all I would need to set up and install a filter, which would be used for many years to come.
The filter itself simply replaces your old panel filter, there is no extra trunking to install. This means that the air going through the filter, is fresh cool air fed from the front of the car. If you are fitting a cone filter, this has to be installed outside the airbox (the housing for the filter), meaning that the air feeding the filter, comes from the vicinity off the engine, i.e. warm or hot, which is exactly the opposite of what you require.
The Pipercross filter is pre-coated with a thin oil, which is designed to trap minute dirt particles. The oil also has a red dye added so you can tell the filter is evenly coated. It is always best to clean out the airbox with a damp rag before installing any filter, and mine has accumulated the usual layer of dust. I placed the filter into the airbox, put the top back on, then went for a test drive.
I was pleased to find that there was no extra noise, in fact there was nothing to tell me I had a new filter. If you are after a sound like a turbine, then this type of filter is not for you. The filter is supposed to allow more airflow, 30% more in fact. I have no way of proving this of course, but I am well pleased with the Pipercross so far.
When it comes to the next service, I have to give the Pipercross filter filter a go over with a vacuum cleaner, then wash with detergent. After allowing the filter to completely dry, I spray with a 75ml aerosol containing the oil. This is supposed to be a simple process, and a light even coating is sufficient. These aerosols can be purchased on their own of course.
I have to say that I am well pleased so far, and when I have re-used this filter three times, I shall be in profit. In the meantime, I will have the knowledge that I am doing my bit the help the environment. I just wish the oil came in a trigger bottle, instead of an aerosol. The kit came in a decent cardboard box, with all instructions.
