has anybody else noticed the unbelievably crappy spark plug wires on the v8 tundras? there is i believe 4 wires per plug of 18g or smaller wire. that's gotta be one strong spark(sarcasm). is there a way that i could change these? im thinking probably not. thanks guys

The Tundra uses a direct coil on plug design. The wires you're seeing do not carry the actual spark energy.

"The i-Force V8 is compact and efficient thanks in part to a Direct Ignition System (DIS). DIS features an individual ignition coil that integrates the spark plug cap, igniter and coil placed over the center of each cylinder, connecting directly to the spark plug. This provides improved ignition timing accuracy, reduced voltage loss and enhanced reliability with only low-voltage wires running throughout the engine bay and fewer overall parts."

thats really cool. i had been trying to find info. on this ignition system for quite some time and never found anything. thanks a lot. but now i have another question, why is the electronic throttle superior? i have an 03 tundra and my friend has an 01 i think, both with i-force. it seems he has more torque of the line. he can do a 30 foot burn out where i got nothin. hmm

All Tundra V8's are "drive by wire", meaning a servo motor controls the throttle butterfly. My '00 Tundra is and my '01 Sequoia is. While they both are "drive by wire", they don't necessarily have the same engine control computer or software.

A quick look at your sig gives me an idea...with the 33's on your setup you've effectively changed your gearing. Unless your buddy has the same size wheels and tires on his, he's gonna smoke you each time with everything else being equal.

This is incorrect......
Only the 2003 and later Tundras/Sequoias are drive by wire.
Meaning there is no physical cable connecting the accelerator pedal to the throttle body. It is computer controlled thru a motor and a accell position sensor.
All 2000-2002 Tundras/Sequoias have a cable, therefore they are NOT drive by wire.
Not trying to start a argument, just informative info.

these folks have come up with an ignition system for the Tundra V8. its a lil pricey though...
is a $1,300 coil system going to REALLY do any thing that great for your money? Doesn't seem to realistic, unless they have a dyno sheet for each aplication to show the benifits.
ooooh bad typing tonight.

I have no doubts it will work. since i own one of their units for my other race car. I have the dyno #s to prove it. I also had one on my raptor when it was "on the bottle" . I do like their system and have had a few live demonstrations from the owner/engineer. I dont think it will be worth it for the tundra until she gets some serious boost or nitro-boogie!

I beg to differ. The simple fact that a cable is present does not mean the operation is not "drive by wire".
My '00 Tundra V8 and my '01 Sequoia V8 each have a cable between the throttle pedal and the throttle body. I have just performed a simple experiment on each one. If the engine is off and the throttle pedal is pushed to the floor and held there, the throttle butterfly rotates about 10-15 degrees. A rotation of 90 degrees is "full throttle". The throttle butterfly is controlled by a servomoter for normal operation and the throttle cable serves as a "limp home backup" in case of failure of the throttle motor and/or control. The 2003 and later simply don't have that backup.
You are 100% correct in the operation, EXCEPT that without the cable installed,the vehicle will not accelerate. Therefore it is not a true drive by wire. It needs the manual input of the cable to operate.
A true drive by wire does not have this mechanical link. IE 2003 and later.

Guess again.
In a "drive by wire" throttle control system, a sensor that is mechanically connected to the throttle pedal tells the engine control computer what throttle butterfly position the driver wants, and the engine control computer then controls the throttle butterfly position via a servomotor. The throttle pedal does not control the throttle butterfly position by any mechanical linkage between the two.
This describes my '00 Tundra and '01 Sequoia perfectly and precisely. A position sensor is mechanically connected to the throttle pedal, via a cable, and is controlled thereby. The position sensor is connected to the engine control computer, which controls the throttle butterfly position via a servomotor. The throttle pedal does not control the throttle butterfly position by any mechanical linkage between the two.
You are, of course, entitled to your own opinion, as am I. My opinion is that the throttle control system on my '00 Tundra and '01 Sequoia is "drive by wire". It matters not where the throttle pedal position sensor is located, and it matters not how it is mechanically connected to the throttle pedal.
new plug wires?
