ok, i just dropped 300 on having the number 8 coil pack and plug replaced. the dealer recommended going ahead with changing the other 7 plugs, but i cant afford it. he also said something to the effect that my throttle body had a flat spot and needed replacing at the cost of 595.

that being said, how easy is it to replace a throttle body with a new stock one, and are aftermarket throttle bodies worth it?

 

for $595 I'd get a 75mm TB, ported elbow but then again I dunno what truck or engine you have so I can't offer good advice

 

sorry. 2004 fx4, 5.4 engine.

 

i just bought the 80 mm BBK, but i keep hearing about the ported elbow, is that something people are just doing onthere own or can you buy it?? i havent done any serious research

 

If u have 5.4 go with aftermarket but if not the just stick with stock put seems little high for stock throttlebody.

 

That is high considering i got the 80mm for around $300. Iwouldn't be surprised if you could find one cheaper either.

 

if you upgrade to a larger TB you'll need to have it tuned and I believe that the Tb bolts right to the top of the intake so no elbow to port
