I have had a K&N filter in my truck for a while now, and its way over due for a cleaning. I was just wondering if I have to buy the K&N cleaning kit, or if there is any other way of cleaning and regreasing the filter. I remember hearing that you could use WD-40 to regrease it, but I'm not sure if that would work.
Thanks for your time.
Save the hassle and buy the kit. Both of my trucks run K&N filters, The kit is cheap and lasts for quite a few cleanings and re-oilings. I don't think that WD-40 has enough viscousity to work properly.
Just my opinion PJL
