Say what? I have a Flowmaster on mine and it hooked right up to the factory exhaust, no problem.

 

I put a flowmaster on mine as well as getting rid of the air box and put a cone K&N filter on it. Also put some platinum plugs in. Could feel difference in power also seems to get better gas mileage. This is a cheap way to get some more power and worked well for me.

 

Yeah i am not looking to go crazy and spend all that money i talked about in the start of this thread. I so far after posting this thread have added a warm air intake that was supposed to be for a pontiac sunfire (a cheap intake off ebay) so i bought that and made some mods to make that fit as well as slightly ported throttle body and removed egr plate on the throttle blade. So back to my point i am thinking of scraping the aluminum tubing that i do have on the blazer now and adding a custom PVC pipe air intake system and a real K&N filter. After this i will port and polish the throttle body and the mass air flow sensor. Once all this is done i think i will do a normal tune up with a little extra you know changing EVERY fluid with higher performance fluids. In the tune up I will change the plugs and wires with higher performance and better quality ones as well. After all this is done i can replace all filters (trans, oil) and make a custom exhaust with a performance muffler i have laying around that is not in use (muffler is for a BMW or something Made by ANSA)

 

I run NGK in my 96 and she loves it! =)

 

Just go out and get yourself a Volant cold air intake and slap the Dynomax muffler. It will be plently loud trust me.
Also, Wynjammer has a fairly inexpensive supercharger for the 4.3L. You would have to do some minor internal work if you want the engine to last, as well as probably a shift kit to keep the rear end a little more precise.
I've seen these trucks eat v8 mustangs on the strip with not much more than this.

 

Why don't our blazers like Bosch plugs??? I just put new Bosch platinum 2's in mine. Are they going to hurt something?

 

they wont hurt anything but youll be replacing them MUCH sooner than a ac delco platinum, in my experience anything bosch in these trucks plan to be doing again within 3-4 months

 

Plenty to read about concerning Bosch plugs, O2 sensors, etc on here. IMO, I would not use them if given to me. I cannot stand doing the same job again in a short period of time due to either crappy quality, gimmick products, or misapplication (universal O2S...).
