Most of the time a person can expect the "get what you pay" for to be the rule rather than the exception. The FL-820S seems to all ways be hailed as THE oil filter to be used as the standard of quality & price. I listen then look for evidence to prove that. I happen to like Bosch stuff for decent quality parts ever since I used to be big into VW diesel cars. Well here I use the Bosch Distance plus D3410 as a comparison to the motorcraft 820S standard.
By weight the 3410 is just under 1.5 lbs vs 15.6 oz of the 820.
Here you see the external can crimp
When you look at the internal cross section of the crip and double the can treads and screw plate thickness, The 820 is looking pretty sad.
The 820 has 50 pleats of media and was extremely opened up on one side of the can while the Bosch has 61 pleats of far more evenly spaced pleats on the left side of the pics.
Here the Bosch as a over pressure by pass valve in its base that in case the filter media were to become blocked or had restricted flow, the valve would let the backing up pressure back into the engine rather than blowing the oil can apart.
Clearly the Bosch is far superior to the 820. When I ban sawed the cans in half, the 820 lost its can crimp to the top and would have leaked like a sieve if it was on the car. The Bosch was just as weld solid as it was before the band saw vibration.
Now on Ebay, the D3410 is costing about 26 bucks each shipped and the filter shows what you get for the money. The BIG heads up here is if you go to RockAuto, they have the D3410 on wholesale for 5.98 each. This is the deal of the century on a fantastic filter for near give away price. I just ordered 10 filters plus a pair of new headlight bulbs to try out for $75 bucks shipped. I have one 820S on the shelf to collect dust from now on!
Oh, and dont forget to hit the web up for the standard 5% off coupon for Rockauto.
