What do upgraded plugs and wires do on are trucks? And what are the best kind to get.Thanks

 

More spark and better current to provide the spark. I'm getting ready to put NGK spark plugs and JBA wires on my truck so I'll let you know how it goes.

 

It is supposed to get you a more complete combustion by decreaseing the amount of unburned fuel that gets passed through to the exhaust. As SC_CHEVY said, hotter and bigger spark.
SC_CHEVY let us know how it goes man, I am going to change mine in the near future, after I get my exhaust done.

 

I sure will smoke! I was very lucky with my spark plugs. I bought them off of ebay motors at a great price. I've received them but I'm still waiting for my JBA wires. I post the results and some pics as soon as I install them.

 

Hey SC_Chevy what kind of plugs were they i was looking on summit website and they have a couple different ones. Thanks

 

Hey Smoke20 does are trucks have a fuel filter? i know my 2000 had one on the fram but i looked and did not see one. Then i heard the 2005s have a lifetime fuel filter. Thanks

 

if anyone cares (lol) i put some Bosh Platinium plugs (the ones with 4 electrodes) in my 4.3L and im sure that it help it burn the fuel better and gave me a little more ooommph ( i cant remember what the old plugs felt like since i did this like 5-6 months ago) im still runnin on stock wires but when i see that the rubber is getting rotted ill put some new ones on

 

Hunt, I have the NGK V-Power TR55 Stock No. 3951

They are high performance spark plugs and are excellent from everything I've read. A lot of NHRA teams use NGK plugs... NGK has a pretty decent website with lots of information.

Hunt - funny you should ask that as I was looking for mine the other day as well to see if it contributed to my lower gas milage. After a bit of a search, I found out it is built into the fuel pump, so we don't have to change them until we need a new pump. Also it is in the tank.

 

Okay good so im not lossing my mind. I dont have a fuel filter that i need to change.
