You cannot use panel filters on the 650s or 12C for that matter.I noticed these are cone filters. I now have a 650s, and previously had a 570s. The drop in filters for my 570 were standard panel filters. Does the 650s only use these cone filters or are panel filters still an option? If either can be used, what do you prefer and why?
This has been a reoccurring complaint with this type of filter. I don't understand why anyone would try to save money on the, relatively cheap (in McLaren terms), OEM filters.Don’t know if this is the case for Mac’s too but coming from a 911 turbo many Porsche owners had issues with BMC filters fouling the mass airflow sensors.
