I bought several K&N 564 filters and discovered that the glue around the top and bottom pleats may not go all the way around the stamped metal and into the pleats, causing unfiltered oil to flow past the pleats. Upon looking at other manufactured brands of these type of filters, they too have the same faults in their glue applications. 2 out of the five paper filters I examined were shoddy in manufacture and one of the K&N filters would bypass unfiltered oil for sure. Inspect these paper filters well before putting them into service. | ||

That is a great (very scary though) information find  . Probably too late for me to check it now but I will ask to see the new ones before they are put in.  . If I were the one who purchased them at a store, they would be returned with a good bit of advice  Thanks ebrfan! |
