Kyle where can I get these injectors for my Blazer. I think that is what may be worng with my blazer!

 

Contact your local GM dealership or purchase them online through GMPartsDirect.com. I have purchased from GMPD.com and their shipping takes FOREVER, but if you can wait, they are typically MUCH cheaper than the dealership. The PN for the updated MFI manifold will get you injectors AT the port, not in the central injector pack, which will not clog up like the poppet valves will/do.

I'd have to see if this spyder is available at my local AC Delco retailer. If it is, I should be able to get it at the GMPD.com price or alittle more and save on shipping and time.

 

They are starting to show up on e-bay but you will have to be careful some people are wanting dealer price for these. I happened onto a lucky find when a 2003 G-2500 van intake for 4.3 was available complete with upper/lower manifolds and injector sets...bought the whole thing with shipping for under $58.00....there was another upper intake from a 2005 4.3 but he wanted close to 200.00 for it there were no bids on that....so keep an eye on e-bay and check with your local auto recycler/junkyard for engines with the injector setup you are looking for and make a deal....

 

Here is the site I bought my Cpi unit from and it works great. Here is the setup I think you need judging from what everyone else is saying.
