OK I`ve been trying to round up Dodge/Chrysler #703 injectors to sell to make a little extra money and have it down pretty good but it seems these injectors only fit Cherokees up to 1999 and not later Cherokees or Grand Cherokees up to date..I have noticed a batch of other injectors that look identical to the 703`s except they have that smaller electric plug in the side..My question is..Is there a more popular 4-hole "upgrade" injector that people usually want for the GC`s and later Cherokees that is found in the Dodge/Chrysler cars?..Part #? Thanks.
