Sup People! I been looking into changing my spark plugs and spark plug wires. I did some research, but really couldn't find anything on the wires. I learned that the IS300 has only 3 wires. So has anyone really use any type of aftermarket wires in their car? I'm just looking for something better than OEM. I found some on NGK's website. But I'm wondering if they would be worth the $$$ to buy em? Thanks to anyone who can help....

not to sure about the wires, i thought that we used coil packs?
there is some sort of amplifier i think i read a while back, not too sure what that does but i would guess it would help on what your looking for.

I am thinking about trying them out. Just wondering if anybody else has put the money down and done it. I was actually thinking about going with the Denso spark plugs. I wonder if mixing the brands would make a difference???

The correct answer is that we use coil packs and coil wires. Three plugs sit directly under the coil pack connected via a boot fitting. Three plugs are connected via wires from the three coil packs. One coil pack supplies spark to two cylinders.

I had a wire go south on me very recently and bought new wires from NAPA 'cause my local Toyo dealer didn't have the one I needed in stock and I didn't want to wait. I don't think you'll see any gains from going aftermarket (I haven't) and it won't make any difference if you mix brands. Aftermarket plugs are expensive. I'd keep the stock wires and spend your money on something else...

Thanks for the info man! +rep
I went over to Toyota and they quoted me $76 for OEM wires. Doesn't really seem right. I'm gonna try to look around and see if there any cheaper ones.
How much did you get yours for??

Hmm...

I got my NAPA ones w/ a lifetime warrenty for $65 I think. You should be able to get individual wires from a dealership. Carson Toyota sells them over the internet. I think they're in CA. If you wanted to go on the cheap I'd just replace wire #1 (cylinder 3) and see if it fixes.

As for aftermarket, I've seen them up to $250 a set. There's just no way to justify that in my opinion.

I think you should do it yourself....
it looks kinda difficult at first but its really not hard at all....

i would recommend using oem plugs and wires...

save yourself the $200+bux they charge at the dealer and clean out your maf,tb while your at it!

*remember where each wire went
*if you're going to use cabe toyota ask for herb, he hooks up the ae86 community all the time.. mention club4ag.com to get a discount.

Just sayin hi for the first time, and also I'm using NGK wires, and can definitely not notice any difference. I bought NGK's because I know they are just as good as oem.
