Taylor 409 wires -photos of hard to find misfire

[Mixmanbob]

BRAZELS put a set of Magnum on mine at about 60,000. We are now at 76000, no problems.

Max you need the fiberglass sock cover on your wires which come if ordered on Tyloe wires.
Have them on mine since 05 in Tenn.
Thanks for the information depudydog.

When I owned my 04 Tiffin built on a Workhorse W-20 chassis we burned up a couple of plugs and wires due to poor airflow with the Tiffin-designed grill. I installed the Taylor 409's and the fiberglass socks as well as making a DIY cool air kit for airflow. Never had another problem but worried about it every time I drove the coach.

Max, I hope all is well for your and your Workhorse out there in Colorado!

I installed a set of GM performance plug wires on my 96 P30 454 and never had a problem. That is until a repair shop replaced the left exhaust manifold and didn't put back on the factory plug heat shields. Drove it home about 2 miles, loaded it up to go to Sturgis last August and only made it about 20 miles before they melted and the check engine light came on. Installed new heat shields and new wires but still didn't run right as the raw gas going down the exhaust fouled out the oxygen sensor. Waiting for spring to add headers and a new set of GM performance wires again.

Tomorrow will be two weeks since I got this email from Taylor and I haven't heard a peep from them:

"I am forwarding the information to our QC and plant manager and I will get back with you after they’ve had a chance to look at the pictures.
Thank you.

I checked in the mirror and did not see a surprised look on my face

Was checking on OEM wires and sent an email to AC/Delco about which of their wires would be the best for a hot environment like an RV. You have to love this response

"Thank you for visiting the ACDelco website.

Hummmm.... now let me see - If the main ACDelco Response Team doesn't have the information about their own parts, who does??? THE SHADOW maybe Awesome technical support Do I detect a foreign accent in this email??

How do I get rid of the change oil now message on my 2008 work horse?

On Workhorse chassis the oil change reminder message is "reset" by pressing the accelerator pedal fully to the floor three (3) times RAPIDLY (within 5 seconds, I think) while the key is in the ON position, but without the motor running. The mesg. "should" flash and then disappear. Don't forget to turn the key switch back OFF after the proceedure is completed.

I just ordered ACCEL 9065C Ceramic Spark Plug Wire Set for GM from amazon @ $117.32.
I read how they are constructed and concluded that they should survive anything that can be encountered on the 8.1 Vortec.
Time will tell.

The taylor wires are fine, even the '409's, just use the stock heat shields they tell you that you no longer need. YOU NEED THEM.

I had a set burn a few early on, replaced them and put the metal shields back on and that was many thousands of miles ago.

I certainly don't share your opinion about the Taylors. They look super-duty but....

I have had 5 wire failures on my Tiffin Allegro Bay in 13,000 miles. Four were Taylor 409's and all had the metal boots installed when they failed. None of the metal boots have any discoloration inside - they are all still nice light brown color so they didn't get all that hot. Three of the four Taylor failures were after installation of the cooling kit. Highest water temp I have ever seen is 206° and generally runs 198° without a/c and 201° with a/c. Most all of my trips are on the road with not a lot of sitting in traffic and only one trip to Virginia of 2,000 miles where I would say we climbed some mountains. I drive generally 62 to 64mph which puts the engine in the max. torque range and I don't accelerate like a teenager.

The one OEM wire failed in the wire insulation itself not in the boot probably an inch above the boot - a tiny crack that let it arc to the manifold shield. No heat damage was apparent on that one either.

Lastly, Taylor support said they would let me know back once their quality control and plant manager looked at my photos. That was over a month ago and still no response! Now that is what I call great customer support!! .

I now have 6 Taylor 409's left so once they crap out, which I am sure they will, I certainly won't put Taylors back on. High failure rate based on my experience and a lot of folks on the forum and poor customer support at least in my case puts them off my list.

I'll have to dig out the receipt to know the exact wire model, when I bought them, and how many miles ago.

Frankly I don't believe how you drive the coach has much effect on wire longevity, but I could be wrong. Here in CA we have to run up and down some grades to get out of the LA basin, and we are usually pulling a load, 3-5K lbs. Just never an issue.

I don't disbelieve you had some legitimate failures, but that you did doesn't lead me to disbelieve in their product. IMO a 5-7mm silicone wire will hold up better than a 3mm stocker. Again, I'll have to check for what exactly I ended up with.

I do recall the instructions saying the boots were good for like 1200degrees or some darn thing and that you discard the factory metal heat shields. I'm really glad I hung on to mine. After a couple of more burnt I found the Taylor boots would fit into the stock shields so I put them back on all the wires. I'm thinking that was like twelve or fifteen thousand ago. I'll check and update here.

I'm also suspect that any other manufacturer is going to be producing a vastly different product, but again, maybe I'm wrong. A miracle material that resists 2000 degrees?? LOL


I will tell you I won't be paying anywhere close to $200 for a set of sparkplug wires.

Not a miracle material - they are ceramic - similar material to a fire brick but with a glaze fired onto it. A quote from Wikipedia " Ceramics generally can withstand very high temperatures, such as temperatures that range from 1,000 °C to 1,600 °C (1,800 °F to 3,000 °F). Take your cutting torch and try to cut a brick - basically the same material Keep several on my TIG bench and haven't burned one yet.

I've seen ceramics on NHRA top fuel dragsters and those headers get hot!!!! (but then again they don't need a WH cooling kit at 300+ mph!) Accel has been around the drag strip at least since the late 60's so they aren't the new kid on the block.

The price he quoted was $127 I believe and that's less than I paid for my 409's if my memory is correct. Also I've seen

I'm not saying they are better, only time will tell but my Taylors have been less than satisfactory and they won't even respond to my inquiry. I didn't ask for anything except a response as to why they failed with no visible external damage and a month plus later they haven't responded after they said they would.

Will be in the pits at Daytona 500 next week - I'll find out what they use. Inquiring minds want to know
