It seems the common K&N Formula Ford air filter is no longer produced or available. There appears that our cousins in New Zealand make a very nice replacement - but its certainly on the pricey side. https://motorsportsolutions.co.nz/pa...r-formula-ford
I have stumbled on another option - The CAL-F1000. https://performancewarehouse.com.au/...1f67da0c&_ss=r
Anybody have any opinions or suggestions?
