Is swapping the intake manifold from a 99 to a pre 99 really worth the time and money? So far i understand its supposed to add more power and throttle response but heres the question: Does it?

 

Its the 00' to 01 intake manifold that get 20-30hp and 2-3mpg not pre 99

 

So a 00-01 swap to a 94 gains 20-30hp and some mpg????

 

I was under the impression all the 99+ manifolds were the same, matter of fact i just picked one up.

What difference is there from the 99 to the 00+?

 

99 and up are the same. Mine helped out greatly, gained me off idle and midrange power and about 3 or 4 mpg.

 

i have a 98 xj classic. i just installed borla headers. while i still have intake i might as well upgrade intake from a 99+ and what about the neon injectors? and what other upgrades could i do to increase power ?

 

Well on my 99 I did the injector swap. I noticed a nice sotp improvement and about 2 mpgs. Before I did it I could only chirp my 235 duratracs. Now I can get a full rotation and a half. Jst make sure she's all tuned up. Also keep in mind of my exhaust set-up in my sig. Right now in mixed driving and this god awefull oxigenated gas ... I get 19.5 mpg in mixed driving and babying it. I don't shift above 2k

 

i just installed the neon 703 injectors, 99 intake manifold and borla header. i still have to finish the rest of the exhaust from header to cat and ill be done and ready to test it out. that manifold is a lil rough to put on w/ header. i had to have a friend come over w/ smaller arms and hands to put lower bolts on

 

20-30hp???? yea right. more like 5-7 hp

 

I'm looking forward to your results. In the next few weeks I am putting on a '99+ intake, 703's, Banks revolver headers and magnaflow exhaust. Our results should be similiar. I also have a 62mm TB and CAI and Superchips reprogrammer.

 

yeaaa, deffenetly not even though i've seen those numbers on multiple forums and other sites

I've seen one site with dyno numbers and there was a 26hp gain in horsepower.

 

Considering 99+ intake upgrade as 94XJ.How is newer intake better?Bigger
ports,better flow path?
The ones i looked at in JY looked the same externally as my stock 94 manifold.
Maybe i wasnt looking at correct year.(grand cherokee)
Anybody got pic or part #? Thanks!

 

The 99+ have twice the plenium volume of the 98 and older intakes.
