Places to buy plug wires and OEM headers?

[jeepbeep]

I have a 3.7 4x4.

Oreilly, Advance, NAPA, and Autozone don't have plug wires and replacement headers on their websites or in their systems in the stores. What's up with that?

A couple have universal plug wires by a company called BWD or something similar. I've found used headers on Ebay that were too used. Not looking for performance headers unless they fit the OEM catalytic down pipes and aren't a large fraction of the actual bluebook of the vehicle like most are.

That's because our engine doesn't have coil wires. It's a coil on plug setup, the coil and drop connector to the plug is one unit. Look for a specific Jeep aftermarket supplier for headers. Don't know what you're hoping to gain with headers though, to make it worth the cost and time.

We have a manifold...not a header. And it looks like they aren't even listed with MOPAR anymore.

EXHAUST MANIFOLD for 2004 Jeep Liberty

And as for wires...we have coil packs that fit over the spark plugs. Not wires as I believe you are referring to. Lots of options to replace the packs...here are some MOPAR ones:

Picture is a bit misleading. They look like this:

Hope this helps.

The reason headers are hard to find is because they only added a couple of horse power. The last ones I saw were around $600.00.

JBA 1930S 1-1/2" Shorty Stainless Steel Exhaust Header for Jeep Liberty 3.7L 03-05

Amazon

^ JBA Performance Exhaust, not to be confused with Jeepin by Al. They're on opposite ends of the country too. Just thought I'd put that out there.
$500 is a chunk of change, not worth it IMO.

Only way headers would help on a KJ is if you " built" the entire engine, then lots of money etc thrown at it and also at WOT you'd need the headers

I have a auto 4x4 so I especially don't care about the 5-45 HP they typically give to cars on various part of the rev. I care because liberty headers have this interesting tendency to develop leaks and welders and muffler shops couldn't care less if they temper them right after welding with running etc..

I didn't know about the coil packs I barely even looked at the liberty internals so far.

Thanks for all the help. I'll probably be asking more stuff soon.

FYI: If you get a header leak don't run it like some guys have here.. You'll need new heads sooner than later it wears out the valve seating super fast and you'll get a rod knock(back-pressure and oxidation and I think even combustion).. Less than a hundred miles with traffic overhead fast..

In over 12 years being on the forums have never heard of anyone with a header leak, now the 4.0s....totally different story

Probably because KJ's have manifolds and not headers :gr_grin:

Is the manifold actually cracked?
going back with Used should be cheap and easy to find locally or eBay.

Very true. Use car-part.com to find used parts from scrap yards in your area.

You know, of all the different issues people have had with their Liberty, I don't recall ever hearing about a cracked exhaust manifold epidemic??

I never have either, thats why I commented, not sure where he is getting his info from. I'd say he's mixing XJs and KJs . Been on LOSTJEEPs, JEEPKJ, JEEPFORUM etc for well over 12 years and never heard of even one , well except for now , but no proof of that yet really

New ones only cost like 50 bucks. Why bother with used.

I thought about swapping in new manifolds when I did my HGs a few years ago but when I pulled the old ones off the heads they were in great shape. At the time this was on a 12 year old 02 with about 150k on it. Just cleaned them up and threw on some new gaskets. No problems since.

That cheap? They look sturdy to start with never thought of aftermarket

Dorman's from Rockauto were about 45 bucks back when I looked. I thought I saw some Mopars on one of those online parts places for about 60 bucks.

When I put in my new engine I put on new manifolds,MOPAR version from the dealer for $40 each brand new.

But in your google searches, were you finding actual instances of cracked Liberty cast iron manifolds, or the more likely cracked (at a weld) non-Liberty steel manifold, a blown out manifold to head gasket, snapped bolts or studs, or a leaky donut gasket?

 

[jeepbeep]

OEM manifolds non-replaced from factory. Typically on the first connection weld. People also seem to have issues with the oil pumps just giving zero pressure pressure do to failure.. Statistics stuff

"manifold"/header leak threads are how I found the forum off Google.. Supposedly they happen do to motor mounts and poor casting and welds.

It's worth noting the only difference between a manifold and header is valve output separation and it's perfectly fine to use either to describe the part as they have the exact same placement and exact same function.. But whatever makes certain types of people feel smuuurter. These aren't performance vehicles so I don't see how it matters we don't need fine grained accuracy for dyno references etc..

If it's a manifold and I say header it takes a special type of person to be confused by that as you can't have both at once..
