eman_be_lexin Posted September 21, 2004 Share Posted September 21, 2004 I don't know how to start but I have been searching for a set of spark plug wires for my 97 ES. Everywhere I have searched I found 1 set of 3 wires for my year. I was told I have to purchase 2 sets to change all the wires. I found the set on Lexus parts.com and they quoted me $84.00 for a set of 3. I thought it was rather steep considering I could have gotten NGK for a little over $90 for 2 sets. I sent an e-mail to the salesman asking about the wires. Here is the conversation: Me: Is the spark plug set for all 6 wires or just 3? Lexus-parts: I just want to be clear, your ES300, 97 year model does not have 6 wires although it does have 6 spark plugs. The set consists of only 3 wires, all the wires you need to replace your spark plug wire set. Should you have any further questions in the meantime, please feel free to contact me directly. Thank you for your time. I then purchased the set of wires and just received them yesterday. Just as I figured, it was a set of 3 wires. I don't understand how a car that has 6 cylinders run on 3 wires. That is just puzzling to me. I sent another e-mail to them about what I received and here is what they said: Lexus-parts: If I remember correctly, we already discussed this over the phone along with email. You received the correct spark plug wire SET as needed. You will not need any additional items or parts to replace your spark plug wires. Please use the following diagram of your wires to help better educate yourself with what is needed. Let me know what you guys think!!

andrecat112 Posted September 21, 2004 Share Posted September 21, 2004 yeah i ran into the same confusion when i was looking for wires for my 98; i had bought a set of MSD wires for a V6 toyota engine i.e Camry(came with 6 wires), then my mechanic told me why they werent compatible..(wish i remembered what he had told me) but in the end i ended up returning the MSD ones for a little more expensive MAGNECOR wires. By the way: ive only seen two companies who sell wires for the es300 MAGNECOR http://www.magnecor.com/magnecor1/main.htm and VITEK http://www.vitekperformance.com/ Quote Link to comment Share on other sites More sharing options...
mburnickas Posted September 21, 2004 Share Posted September 21, 2004 I got OEM wires and had zero problems. Also got Denso plugs without any problems. I got my items from http://www.allimportedparts.com/...they have it for $43 for a OEM SET! Quote Link to comment Share on other sites More sharing options...
eman_be_lexin Posted September 21, 2004 Author Share Posted September 21, 2004 Mburnikas, Did you receive 2 sets of 3 wires or did they come as a 3 wire set and that is it. I just want to make sure I am either right or wrong about this. Quote Link to comment Share on other sites More sharing options...
mburnickas Posted September 21, 2004 Share Posted September 21, 2004 my 98 had 6 wires or 2 sets with 3 wires. Quote Link to comment Share on other sites More sharing options...
SKperformance Posted September 22, 2004 Share Posted September 22, 2004 I know in a 96 and 97 and am pretty sure up from that year on a 1mz-fe engine ,their is 3 plug wires which are for the rear plugs, the front ones are all coil on plug so they do not use wires.

sunman Posted September 22, 2004 Share Posted September 22, 2004 That is correct. My 97 with 1mzfe engine has only 3 wires for rear plugs. Front plugs have the coils directly on them. I replaced mine with NGK Iridium Plugs for 45 bucks. Quote Link to comment Share on other sites More sharing options...
eman_be_lexin Posted September 22, 2004 Author Share Posted September 22, 2004 If i am changing the wires, do I need to replace the coils as well? Quote Link to comment Share on other sites More sharing options...
SKperformance Posted September 23, 2004 Share Posted September 23, 2004 no coils only get replace when they go bad they are not a wear item like a cap and rotor Quote Link to comment Share on other sites More sharing options...
eman_be_lexin Posted September 23, 2004 Author Share Posted September 23, 2004 You all are a great help. I was getting upset for having to spend another $84 bucks on the wires again. I have NGK iridiums and the new plug wires. I will be getting them installed this weekend. Thank you all for your input. Quote Link to comment Share on other sites More sharing options...
elogan72 Posted February 23, 2009 Share Posted February 23, 2009 That is correct. My 97 with 1mzfe engine has only 3 wires for rear plugs. Front plugs have the coils directly on them. I replaced mine with NGK Iridium Plugs for 45 bucks. Hi, I am new. I am also a woman but know a little bit about the workings of my 1996 ES 300. When replacing wires back on the new plugs, just how do the wires go in relation to the 3 back plugs? If I am understanding correctly, the wires are of various lengths, and the longest wire goes to the plug farthest away and so on. Can you confirm this please. I would really appreciate it.

This is probably late to need but I could not find this answer posted anywhere. I had a similar question on my 96 ES300. I found a diagram on AllData and deduced what the wire connections would be and, after I installed in the following manner, I did not throw any codes for misfiring, etc. Here is the cylinder layout Firewall __________________________ 1 3 5 2 4 6 _________________________ Front of vehicle Coils are on # 2-4-6 cylinders (3) Here are the coil to wire connections. 2 => 5 4 => 1 6 => 3 Hope this helps Quote Link to comment Share on other sites More sharing options...

dwp1220 Posted August 1, 2009 Share Posted August 1, 2009 Yikes...lol Hi Lexusfreak.. I know its an "oldie but goodie" revival but since I could not locate it anywhere else, I thought it might pop up if someone should "search" the forum for it. Thought this thread would be appropriate. Do you recommend I start a new post on this? BTW, great forum. It sure has helped me. Lurking can be fun!!
