Banks Header

[Jeep Driver]

Anyone have any experience with Banks? Worth the money?

 

 

Any reason the Wrangler will not fit the MJ?

No personal relationship with headers of any kind. BUT, everything I have ever read says they only do good at higher rpms. Any low rpm gains are very, very marginal. If you go screaming down the street or trail at 5200 rpms, then perhaps you get a few extra horsepower. Otherwise, save your money and buy an extra 100 gallons of gas.

51316 will NOT bolt upto the MJ/XJ platform. You may be able to fit it to the head, but it will require a custom down-pipe.

5, but it will require a custom down-pipe.

 

 

Well of coarse.

That's really what I wanted to know........was there any head changes between the years?

That is one of those "conventional wisdom" things that in many cases is not true at all. You can read constantly about something because the people posting te info just "know" their info to be true so they pass it on. Actual back to back dyno testing on various set-ups has proven that there is no single answer to the header vs. manifold debate. A recent study of a 360 AMC V8 in a FSJ using stock manifolds, "shorty headers," and full-length long tube headers showed solid increases in both HP & TQ with the long tube headers over the stock manifolds.The popular (and more expensive) "shorty" headers had little to no effect on HP or TQ. The greater the other mods ( carb/intake/cam) added to the engine the greater the increase in HP & TQ over the stock manifolds with the full headers.

 

Like everything there is a balance. Some factory set-ups may be better than others to start with so there would be little difference after the header swap.
