Spark Plugs, which ones? Need to know ASAP!

Getting either Bosch Quad tip Platinum or Iridium for my 5sfe. Which ones should I get? $20 for the Bosh, $60 for iridium, worth the difference? Thanks.

I would just get standard or V-power NGK's. I have never seen any benefits to the more expensive plugs. Actually the more expensive plugs don't agree with boosted engines..

You would think it wouldn't matter because as long as they spark then you're alright. I guess the main difference is how long the plugs last for.

i know that for the v6's toyota reccomends iridium (100 000kms life span)

get the iridiums. i've got em in my 89 3sfe. they give you a bit better gas mileage and slightly improved throttle response. and they last 100-120K. if you get denso's the part # is IQ16.

I ended up getting the Bosch Quad Tip Platinum. Man, either they are that much better, or my old spark plugs sucked that bad. Starts so smooth now, and seems to rev easier. Supposed to last for 100,000 miles to. Best $25 I ever spent on my car.
