But Airaid does.

 

ASP makes a pulley for the 4.2.

 

Press 1 for ENGLISH,yall

 

with a doubt, exhaust and then get a sweet purple spoiler nd then a big sticker that says rice burner

 

depending on how much you are looking at spending, here is a list of things that will help:

-Dual 16" electric fans
-Custom/Dyno tuning (SCT or Edge)
-Gotts Mod
-2.5" exhaust upgrade (muffler and pipes)
-gears (if you plan on up your tire size)

 

What's gotts mod and what's the e fans do?

 

The Gotts mod is a cheap and easy mod to basically increase the airflow of you stock intake system, while still retaining the protection of the filter from the engine heat. If you do a search for it, you will find plenty to feed your brain.

Electric fans (e-fans) are a very common, and extremely cost effective mod. No matter what vehicle you have, Efans will be a huge gain compared to any other performance mod.

You replace your mechnical clutch fan with 1 or 2 electric fans, of appropriate CFM rating. This frees up a lot of drag at driving (40+mph) speeds because the fan is not limited to spinning as fast as the engine is. Instead they are free to use the force of the air moving across the radiator to spin them, hence keeping your radiator cool, while allowing your engine to do nothing but move the truck. Typical MPG gains can be anywhere from 1-2 city and 2-4 highway, depending on driving style. It also gives you a much stronger top end, and some people see as much as +15 rwhp in the upper RPM range.

 

anyone have recommended e-fans for the 4.2? I have a 2006 4.2 and would like to do e-fans.

 

Troyer makes a kit, but for $275, you can build one yourself just as reliable.

A lot of people seem to use the SPAL fans from the new F-Series trucks nowadays.

I bought some ProComp 16" fans off eBay. But the motors siezed and burned up for some odd reason, not sure why. Flex-a-lite also has a kit.

Do a search on this forum and you will find all the info on kits/installs that you need.

 

2x 16" Hayden Fans- $75
1x 30-amp, single-relay Hayden controller- $33
2x 4' aluminum strips (cut in half, makes 4 strips, then trim and drill)- $6
8x screws and nuts- $2.50

 

Will this same setup work for a 98 4.2?.... Also what about the fan shroud? Does still need one or no?

 

My truck IS a 1998 4.2L. Do you not read the siggy?

No, remove the shroud and mechanical fan

 

Is that a mini-fridge in your room? Cold beer in the morning. Awesome. What does your mom say about that?

 

I didn't notice as much of a difference with the 4.2, but on my 5.0, e-fans, CAI, & exhaust made a huge difference. But the big improvement on both cars came from custom tuning.

 

I bought the Troyer Kit. I would recommend the Troyer Kit. It worked out well for me.

As an alternative, look at Derale Cooling Products 16927. About $265 from Summit Racing and Jegs.
