i know this is a stupid question but for a b16 sir2 can u use a gsr oil filter cuz eveyone tells me there all the same but then when i took filter off that was on there is just happend to be mobile 1 filter the numbers were different but i didnt look at it and put the gsr filter on there

 

they're the same. 3593. some companies use different numbers, but they're still the same.

 

cool thanks cuz when i put the new 1 in it felt perfect but it felt bigger and the old filter was longer i know im ******* paranoid

 

they're all the same
