Well, I suppose if people don't buy this garbage, it won't be a problem and we might see fewer of them.

Then again, shops want cheap.
 
2.84 $ is a bargin and it is a fair offering !was scared it would be prone to sticking but seeing the shape it just cant happen! was installed today we ll see tomorrow or tonight in the cold how car sound

I've lost track in this thread but are you talking about the Toyota OEM filter? If so, then I have used then almost exclusively on both my Toyota cars and they have started at -25 degrees Fahrenheit with no abnormal noise.

Edit: Never mind, I see it is another filter.

a bit of a recap, i had a nissan filter, an ultra fram, a tg fram and always i heard an initial dry start ( you ll know what i mean if you ever heard one)this morning i cold started ( 14 faren) so its cold.and now it does not do the dry start anymore it sound like and engine should sound. ( FINALLY, WAS BEGINNING TO THINK NISSAN HAD GONE DATSUN MODE)
is it the silicon bypass at the screw end ? or the inerent way a st 6607 work?( other similarly are posted here so no need to post) one thing is sure problem is gone.so for me case closed( remember that my nissan has a front mounted ( just beside the radiator horizontally mounted so if your vehicule has a similarly mounted filter this might help) this is my initial view since i dont know how things will be at next oil change.but for now ? problem of initial dry start is gone! 3 cheer for supertech

+1

Silicone is better, but I haven't experienced any issues either using oil filters with nitrile ADBV's.

Silicon seems superior in everything I have seen. All the premium filters use silicone & the budget filters use nitrile if that tells you anything. I'm no expert though.
