Recently my T100 V6 5VZFE broke down on me complete with blinking CEL. Scared the snot out of me since I thought I broke something in the motor. I was able to get it to my local Toyota dealer and they scannned it. It was throwing a misfire code on cyl#6. They said it would need new plugs+wfires. but they claimed they had no genuine yota wires for it in stock. They wanted me to leave my T there over the weekend until they got some delivered.
I told them to install some after-market wires and get me out of there. The service mgr. stated they would not guarantee the work since they have experienced problems with non-OEM wires. So I watched the Carquest guy bring my wires into their shop and when they were done I drove off w/no problems. The last set of wires I put on my T were Bosch purchased at Advance Auto. They lasted about 2yrs and 28K miles.

Can anyone verify that genuine Toyota wires are *better* than non-Toyota ones? And if this is true then what is so special about them that make them better?

 

The guy you want to talk to is Trainwreckinseattle, he has done a lot of research regarding OEM vs. Aftermarket.

If you merely compare the two side by side, you will be able to tell the difference. For a "get you back on the road" situation will it matter? Not much. But in the long run, it does make a difference. Different resistance readings lead to premature coil failures, and OEM wires are just simply made better. Better quality, and better quality of materials.

 

Unlike alot of people on this site, I gotta go with the service manager on this one. In my experience at the dealer, nothing worked as good as genuine Toyota parts. I can't tell you how many time's I had an older Toy come in with a missfire that had non-Toyota wires or plugs in it. There's a reason Toyota used NGK's and Denso plugs and wires. They work.

 

A least on the 22r the oem wires came with the spacers installed no comparing lengths, just plug and play. When I went to buy my wires at the dealership the parts guy was asleep behind the counter ,and I guess it embarrassed him because he gave me the business discount on the wires.

 

Most aftermarket plug wires are junk but one brand that has served me extremely well is NGK. You can get them ordered at Advance Auto. Should only take them a day to get them. Also do not forget the coil plug boots for the passenger side.

An OE wire set should be good for at least 100K miles, if you only got 28K out of your last aftermarket set before they started misfiring then you answered your own question. If you take what you spent on the aftermarket wires, plus what you paid the dealership when they failed you could have bought a set of OE wires the first time and saved yourself a headache.

 

RockAuto.com has NGK for TX99A 22r 22re for $23

 

Thanks for the responses guys.

JamesD: regarding the coil plug boots for the passenger side, do you need to get these new or can you re-use the existing ones? And you need only THREE, correct? The prices one of these are confusingall prices from Rockauto)
NGK Part # 58931 {#CPBT003} 3 Required $13.90
BECK/ARNLEY Part # 1751017 Multi Coil System $27.79 ???

250000_yota: So Toyota's OEM parts are really NGK's and Denso plugs and wires that can be bought at most auto part stores? I cannot tell what is what on Rockauto:

NGK Part # 4412 {#TE66} 3 Required $25.79 (three wires w/boots) (this seems to include only three wires w/boots? There is no corresponding part/kit for the other three wires...w/o boots.

Likewise with Denso - there are two products listed, one looks like 3-wires the other six but only about a $4.00 difference between them:

DENSO Part # 6716182 Primary Ignition Wire Three Lead Set;Application Requires (1) Three Lead Set Complete Ignition Wire Set - 5mm $29.79

DENSO Part # 6716248 Primary Ignition Wire Coil On Plug Boots; Application Requires (3) COP Boots Complete COP Boot Set - 6 $33.79

 

And I haven't even gotten to the plugs yet. Rock lists ELEVEN different Denso and NGK plugs for my motor and it's spread out among Copper, Platinum, Double Platinum, and Iridium. How would I know which is the *best* plug for my motor or which ones are closest to factory OEM?

 

The funny thing about headaches is you never know when you're going to get one. Had I known all this stuff before it happened I would have done the right thing in the 1st place. But that's how I get my best learnin, not from no fancy book, from the road of hard knocks(and I don't mean my motor).
