Thanks ASM.
My friend who usually services my car said he could get front pair for $171 but told me to shop around to see whether i could get them cheaper. Not sure whether they were OEM or what brand. Guess i ll just ask him to get it so i wont have any issues in case if they dont fit, he could get them changed...
Btw ASM, off topic, i saw you sold your air intake. How was it when you had it on? any noticeable power or sound improvements? researched on g37 and Takeda LTCAI seems to the one to get or Rc2 but then its a short ram intake. Would cost close to 1k with shipping and conversion though..
