My bro hooked me up with some NGK Irdium Spark plugs at dealer price of only $5 each instead of $12. But they are only single elctrode. Should I use them or go get double electrode plugs?

 

i dont see a point in upgrading spark plugs if you have a N/A motor.

I would get the stock Denso Dual electrodes for 2$/each

 

What do you mean by N/A?

 

naturally aspirated.

I would stick to factory plugs/wires. If it didnt come with them from the dealer, I wouldnt bother.

 

Agree with Localmotion... unless you have a supercharger etc. you don't need to upgrade to those Iridium plugs. Just stay with the Denso/NGK dual electrode plugs and OEM plug wires and you're good to go.

 

dual electrode plugs last longer ... i payed 18 dollars for 6 denso dual electrode plugs at the dealer and got a set of ngk wires for 37 dollars

 

Cool. So I should return the plugs, get denso OE, And possibly upgrade my wires. I'm at 138,000 miles and I'm sure they are the stock wires.

 

i replaced my stock wires at 132k and was still running great and pretty sure the plugs had 25k or more on them i figured it was time for a basic tuneup

 

If you've moded the engine i.e. cams, added a supercharger or moded other parts in the induction system, increased compression ratio or upgraded other parts of the ignition system i.e. blaster coil etc. then it makes sense to upgrade the wires if not.....stock is fine! Same for the plugs, if your running a stock motor...its a total waste of money to run anything more than stock!

 

word ... i would of went with stock denso wires but the stealer wanted 60 bucks..... and be very carefull with the clips on the coil that hold the sparks plugs i broke 2 of mine cost me 10 bucks for 2 new ones

 

I just did the intake and deckplate mod. Now I think I started a chain reaction. And to think my girlfriend thinks I have an expensive hobby now. Who know's what's next!

 

18'' magnaflow muffler ?

 

Good idea, and affordable.

 

it well make the intake quiter not sure if girlfriend well like how loud it is though

 

She doesn't even like the $Runner much. She won't even notice, maybe. BTW It's funny that $ and 4 are the same button.

 

Our 2001 Tacoma with the 3.4L has a sticker on the timing cover that says to only use dual electrode plugs.

 

so does my 4runner

 

I install some NGK 4 pronged spark plugs and it really woke up my engine and I get better gas milage.

 

I installed SplitFires in my '76 20R and it made quite a bit of improvement. Response, Hp and MPG.

 

There is a dealer sticker on the timing belt cover that states to use "Dual Electrode Spark plugs"
