i work with cummins and caterpillar engines.. all the filters are either from mann or donaldson.. and the quality of those filters as compared to guard is massive..
on the other hand guard is massively better as compared to genuine SGP suzuki filters. i my self have used guard filters for quite a long time.. currently have leppon in my civic..
advantage of genuine made in japan or thailand honda part is that you can use it to 10k km with a cleaning interval in between.
for guards you have to replace them much sooner.
