Let me explain why I believe Pipercross to be the best air filters for the enthusiast looking for increased performance and engine protection.
After spending quite a bit of time researching into various performance air filter solutions for the Fabia vRS, I finally decided that the Pipercross panel filter was the one for me.
So why Pipercross?
Firstly, it’s an OE replacement filter which means it’s designed to fit to the original vehicle’s airbox and doesn’t require any modification of other parts. That makes it good for cars under warranty as well as insurance companies.
…doesn’t require oiling
Secondly, the Pipercross air filter for my TDi Skoda doesn’t require oiling. That’s probably not a big deal to most people but for owners of engines with Bosch air flow meters (MAF sensors) it can be a big headache when oil from a filter contaminates the sensor causing it to send false signals or fail altogether.
Pipercross listened to their customers and developed a specification of foam which could run dry and is now the filter of choice over greasy rivals like K&N, Green and BMC where some VAG specialists are concerned.
Third, I can run the foam Pipercross filter for 25,000 miles without having to worry about it clogging up and starving my engine of air. With standard paper filters and cotton-gauze filters like K&N and Green, dirt starts to clog the filter as soon as it’s fitted thus compromising airflow.
Thanks to it’s three-dimensional nature however, foam allows air to bypass blocked cells (cells that have trapped dirt) and doesn’t restrict airflow until it’s full loaded.
In researching air filter options, I discovered that cotton-gauze filters can become noticeably ineffective in as few as 2,000 miles of road use! Green even state in their instructions that their filters require cleaning after 5,000km (3,100 miles) which is pretty pointless for a car designed for every day use in my opinion.
Fourth and finally, cleaning. When the time comes to finally clean the air filter (roughly every two years for me and my Pipercross filter), all I need to do is tap off any loose debris and armed with a Pipercross cleaning solution (C9003 if anyone’s interested as I don’t need the oil that comes with their other cleaning kits) spray the cleaner over the filter and run under the tap. Once the dirt has all gone, the filter can be patted dry with some kitchen towels and then popped back into the airbox.
The cleaning method for an old K&N filter I had on my Vauxhall Nova was horrendous and needed all manner of bottles, trays and devices to sufficiently clean and re-oil the filter. If the K&N is over-oiled, it doesn’t work. If it’s under-oiled, it doesn’t work. No thanks.
As you’ve probably guessed, I’m a fan of this Pipercross filter. I did consider other air filter manufacturers but as it’s my money and time I didn’t think their products were all they were cracked up to be. If I was running a race team with a supply of free filters I might be tempted by K&N or Green but for road use the Pipercross filter cannot be bettered in my view.
Saying that, if I did have a race team, I would be speaking to Pipercross to get a different grade of filter (they make different types for road and race use) that was more in tune with my needs.
