just did an oil change, changed ujoints and put a flowmaster on my wifes runner. now i want to do something to the intake. ive looked at the tech faq's, and found 2 or 3 different mods i can do, which is the best one to do?

 

well, what year is the 4runner. 92?

 

yeah, its a 92, 2wd auto v6

 

ISR mod... IMO. Simply because you retain the stock airbox (which is more water proof than just an open filter).
