I don't know if they are worth the money. it would seem for every positive review I find a negative review. Some say the drop in filters are worthless, some say they work. Others say the only way to go is the complete air intake kit, others say this is worthless too. I've got an 07 tacoma and some even say that the K&N filters fuck with the MAF sensor. SO I dunno. I just know I need to give that 2.7 liter a bit more pep.
