99 blazer intake manifold
 

ive got a 99 LS 4.3ltr 4x4 Blazer & am wondering is there any aftermarket intake manifolds available for these engines?
id like to still use the injection,just wanna get it to breath better
Cheers

only option I'm aware of is a marine intake.

hate to link to another forum, but this is a good one...

4.3L Vortec Marine Intake Conversion Helpfull Hints:

Cheers Blazen :icon_beerchug: ive seen Edelbrock do one also, a PN2114.
but i think it suites a 4 barrel carby not fuel injection. i was just lookin to see if there was one available to help the engine breathe abit better without goin over the top. Im also really not sure about changing the engine from fuel injection to carby.
Im in Western Australia so getting info & parts isnt the most easy thing to do haha
