is there a certain year span for the injectors to fit in my 99 4.8. I was wondering if 06 injectors will work or not. tried the search but didnt have much results.. later tj

 

I am pretty sure they are the same, the 8.1's should work. I ahve some out in the shop but am to lazy to go look rite this sec..

 

anyone else? need to put bigger injectors in. any other suggestion are welcomed.

 

someone has to know the answer. what im asking is that 99-02/03-06 or 99-06

 

Check part #'s for the 8.1L injectors, see if there are different part #'s for different year 8.1L's. Start there. If one size fits all, then any year 8.1L should fir your truck. Call a dealerhsip to confirm this though.
