yaris9876 · 01-17-2009, 01:11 PM

I buy NGK platinums and head out to the 07 Yaris(140K) and pop the top off
and go for the plugs and this weird thing is what I find...
what is it? it doesnt look like it needs replacing and if I had to what would these stupid
things cost..???The guy at auto zone didnt say a thing to me.. just gave me the plugs..

Just to help you out, it's called TDI. Toyota Direct Ignition. I used to build the Toyota engines in a factory. You don't need to replace them at all.

Black Yaris · 01-17-2009, 05:41 PM

it is called a coil on plug set up... the ign coils sit on top the spark plugs

ztrack157 · 01-17-2009, 06:27 PM

They (coils) don't need replacing. But man clean you engine of once in awhile. My car is flithy right now but you can eat off my engine.

welcome to 1999 :)

it's been more than 10 years toyota has used coil packs instead of spark plug cables.

coil packs and coil on plug are 2 completely different things.... cars with coil packs still have ign wires

UTVitz · 01-17-2009, 08:35 PM

Yep, coil over spark plug-most newer cars have them now. They just make it a little more time intensive to change the plugs-no you don't replace them and I have yet to have one fail even on a 10 year old Jeep Grand Cherokee with 200K miles on it. Your car should have NGK "iridium" plugs, not "platinum" The iridiums are designed to last 120k miles-I don't recommend going this long even though Toyota does, but the car is long out of warranty by then-so I'm changing them at 60k miles. Iridiums cost $10-15 per plug from what I've seen. I'm not sure if the Yaris will run right on the platinums-try it and see. I did some research on iridiums-they have a much longer life that platinums-which are a step down in quality to the iridiums. Good luck.

Oh, if you do decide to clean your motor-don't get water down these holes or you'll ground out the plug-I did this to a Miata once. I clean my engine off with the black cover over the motor then I don't have to worry about it.

yaris9876 · 01-17-2009, 09:17 PM

so I need what size mm deep socket for this???? And there is no way that platinums wont work..
iridium is expensive hype... there is so little iridium on there you could count the atoms.
its a drag you cant even get your head into over the holes to look into there..i would have seen the plug tops...

platinums will work, they will not last as long... I hope you bought NGK/Denso plugs though

You arent aware of individual ignition coil packs, and next your counting Ir atoms on your plugs? Get the Ir plugs. They are the biggest ignition advance since DLI and will run better than anything on a stocker. Toy typ uses Denso - they are better made than NGK. NGK has terrible GND electrodes that glow and burn off in these lambda motors. Bosch make a very good standard copper plug, everthing else is absolute crap. These DLI ignitions are actually WEAK, they need the small electrode utilised in the Ir plugs to prevent excessive misfire. Donty think you can outsmart the DENSO IGNITION GUYS.

why be cheap on something you buy every 8-10 years.

Black Yaris · 01-17-2009, 09:24 PM

this is from alldata

mimelio · 01-17-2009, 09:59 PM

Anyone ever see Bosch Iridium plugs? They have the four ground electrodes

Junk... we sell them at work..... if you know anything about electricty, you know that the spark can only pass though one ground at a time, so why are there 4... and why does no other spark plug maker use it?

all a gimmick

YarisSedan · 01-17-2009, 10:18 PM

Bosch will make your car run like crap. If you use a platinum they will not last as long and then your coil will eventually burn out as it tries to fire more power trying to jump the excessive gap. And they can run several hundred a piece. Just buy the oem ngk or denso iridiums. ANd return the platinums

mimelio · 01-17-2009, 10:25 PM

Never ran them in Yaris just saw Bosch made Iridium plugs with four ground electrodes. Iridium is by far better than platinum...One more plug I saw was Pulstar http://www.pulstar.com/howtheywork.html they are expensive too.
