This may be a stupid question, but can someone tell me where the spark plugs are located on the Xb?

 

Take the black engine cover off and you will see the 4 holes where the plugs are on top of the engine.

 

I had the cover off i didn't see them. Do I have to take off the metal covers?

 

No ,there is four holes with rubber like grommets or boots, you pop each rubber boot off and look inside and there is the spark plug. You will also see, i beleive it's two wires going into each rubber piece. Im trying to find a pic for you.

 

Okay go to the tech section under features. Click xB, scroll down to spark plug replacment and click open tech article.
once this opens scroll down and there are some really good pic's of where they are at.

 

nevermind i found them. different from the kind of plug wires i'm used to seeing. thanks for your help. Another question. I bought some blue wires. Will they work with this car because it looks like they are all wired in the same harness?

 

Blue wires????

 

Yeah they are 6 core wires. They look like the kind thst just go to the dist. cap to the plugs with straight boots. Now that i see tha set up on these it doesn't look like they will work. It said they were for the xb.

 

Yeah, they wont work that i know off. Nology i think its called makes plugs for our cars, but there is alot of pro's on cons with them, depending on who you talk to. Ive also heard that the they way or plugs are set up is one of the best ways to have it.

 

Yeah, that's what i thought. I didn't even think about looking at it first since they said it was for the scion xb. Guess I got ripped off. Thanks for your help. The NGK iridium plugs will at least work. Thanks again.

 

For future reference the xB's 1.5 liter engine uses a coil on plug design. Adding any type of spark plug wires, even the best most expensive in the world is going to add resistance. This in turn means you have a very good chance at reduced power and efficiency. (Anything to make a buck right Nology?)

Also, unless you are looking for longer life out of your plugs, there is no need to switch to iridiums or platinums. All they do is prolong life, and I have heard statement that in some applications they can actually reduce efficiency and power compared to a standard copper plug. If you are planning on changing your plugs at standard intervals, your best bet is always a properly gapped copper plug. In some cases, such as forced induction, switching to a "colder" copper plug can prove beneficial.
