    Throttle Body Spacers

    Hey guys I was hoping to get some opinions on whether or not Throttle Body Spacers really work or not.

    I am looking to maybe add one to my 04 S10 Blazer 4.3L with a cold air intake kit already installed!

    Save your money get a set of headers for it. Adding a throttle body spacer is not going to add much if any power..

    The blazer is 4wd and I have only found oem style replacement headers except for a few shorty headers that are over priced. I was also thinking about a ported throttle body too.

    I am really just looking to add a little more power to the 4.3L and any suggestions would be helpful.

    Since the intake twists and turns in the blazer, a throttle body spacer isn't a bad idea, helping concentrate airflow. But, there isn't a hug need for this process (if it even works), so it's more of a waste of money than a performance upgrade. If you can get 1 for really really cheap (<$50), I would do it. Otherwise, follow everyone elses advice.

    It makes a sweet whistle noise

    I wouldnt do it, they are basically a big joke, kinda like the ebay "chips" that offer 300 horsepower and such and are nothing more than a resistor for your AIT sensor...

    Build a 60*v6 for it and sell that 90* 4.3. A 3.4/3.5 hybrid would be a far better engine for performance, and there's an after market for them too. Not all of the 4.3 90* v6's even made 200 hp. There were various packages of the motor and most do'nt even make 200 hp. It's only a matter of time before they will be replaced with a 60*v6 anyway. The 90* v6 motors are going the way of the dodo bird. The 3800 was replaced in Camaro with a 60* v6 aswell.. That's why I'm building a 17 year old 60*v6, and the 3800 boat anchor in my 01 Camaro stays stock. Next year the motor gets sold while an lsx package replaces it. However all is my opinion, from what I've seen with over 18 years of messing with v6's.. IMHO if you're going to mess with a 6 build a 660.......I'm not putting your motor down though, build what ya like. I'm a v6 guy myself, love v8's too, but the 660 has a special place with me. They all have their probs, and I've driven many different types of v6 powered stuff. I always come back to the 660.............

    Oh you can always go to a v8 too...

    spacers are proven to work on carbed motors but never do anything for fuel injected.
