Air Intake and Exhaust

I know there is no deffinate right anwser to these questions but I wanted to get some opinions though.  What is a good intake to get.  Are the ebay ones any good? What is a good exhaust to get?  What size piping for both.  Also I have been reading that you should do intake exhaust along with the spark plugs all together to get good results..  What kind of plugs?  Also should this include the wires too.  Thanks for the help.

Ok, well I have heard people having great results from k&n but I have heard people say dont waist your money on the expensive intakes and just buy an ebay one that includes the heat shield. Personally all I am going to do is buy the ebay one with a heat shield. For spark plugs go with AC Delco, lots of other people on this forum will probably say the same thing.  The biggest restriction on the 4.3 is the exaust manifolds so you can upgrade your exaust and intake but you wont notice a huge improvment unless you get bigger manifolds.

I put an ebay air intake on my wifes 01 jimmy and have no problems with it at all.  I plan on fabbing up a heat shield for it out of aluminum to make it a "cold air" intake.  I don't notice any HP gain, but it does look and sound pretty cool

Thanks guys for the input.  Keep em coming

Yeah any one off EBAY will work.  Just make sure to get one that eliminates the rubber tube.  That tube is a large restriction due to the ribs.  Click on the attachment to see mine I bought off  EBAY.  Korey

Kordog, what are you talking about. Your intake looks like it has a few rubber boots, so what exactly are you talking about?

Yeah, but those rubber boots are smooth inside unlike the acordian tube sections on a stock intake.

Well this is good news, but one question: I'm looking at these "eBay" intake kits, and I am impressed, but, what provisions for the electronic sensors are there?

where did you get that intake that is what i am lookin for exactly what i am lookin for

That intake has no provision to draw in fresh outside air.  I highly doubt that is doing any better on a hot summer day than the stock air box with paper filter.

It is not yet done.  I will be adding an air box to shield the filter from the hot engine.  I have not really used the intake yet on any hot days, since I just got it installed in Oct.  Just like Kyle said, that acordian section, between the TB and MAF, is the part I was refering to.  Sorry I did not go into detail on my last post.  But these intakes do flow allot more than the stocker, just look at the little hole in the front of the lower air box.  That is all there is to introduce air into the factory airbox!!  The IAT sensor has a hole drilled into the upper tube and is held in by a rubber grommet.  I had to do a little adjusting to get  the fit I wanted, but all in all it is a pretty good kit for the low price!!  In my opinoin it looks better than the black K&N tube also.  Like I said before, make sure to get the kit that eliminates the acordian section,  I have seen some that just replace the airbox before the MAF.  Those acordian sections cause turbulence that restricts flow.  Korey
