Newbie here
just wondering if i should go for the iridiums or bosch 4 spark plugs. any input on either plugs would be super. Thanks.

oh, it's for a 93 runner V6.

Stay away from the Bosch 4's, they are garbage. I've never ran iridiums. I've ran quite a few plugs and the best performing plug I've had in my runner thus far was Champion single platinum. I am running Champion double plats right now and at 5 bucks a pop I am not impressed. In a couple months I will switch back to the singles.

the iridiums are awesome... the denso and ngk are the best for the toyotas

I get great results with just OEM plugs but ditto to the above as well.

ngk's here, got em for $4 a pc at napa. I agree that the +4's are a hustle.

Denso Iridiums are the best plugs I have ever run in my 94 3.Slow 5 speed.they really work great for me !

you really don't need iridium plugs(and they're expensive!) on the older engines, some of toyota's new engines like them though.

NGK or denso are the only brands to use for plugs and wires in a toyota, at least with factory ignition. i've heard autolites and delcos are good with MSD ignition though(seems to make sense, not mixing american and japanese electronics)

bosch in the toytas sucks

Stay away from all Botch products--go with NGK or Denso.

I would stay away from iridiums... They have been known to mess with the 3.0's idle. I have the NGK V-Power which is their basic OEM plug but it has an electrode with much more center edge to fire from. It made for a very smooth idle nad run great in my engine. I used to use champions and they were not near as smooth. The iridium and platnum is just a waste of money on these block in my opinion. Get NGK wires and the NGK V-Power plugs and you will be very happy.

I would recommend OEM plugs, they are a lot cheaper than Iridium and run as well!

No! Bad ju ju! stay away! Buy NGK plugs. They last much longer and work better.

NGK plugs are awesome! I recommend them.

installed denso iridiums yesterday on my rig. i was skeptical prior in these plugs for the price, but it was time for new plugs and wires. i noticed my motor idles smoother and feel there is an improvement (had splitfire plugs before).
another vote here for denso iridiums..

I think i'm the only person on this thread with Bosch +4's, but dnt buy them. They seemed to play aorund with my idle, and starting the car in the cold, and sometimes when the engine is hot, is a pain in the a**. But at least i didn't pay alot for them, i got them when they were on sale. But overall, i wouldstick to ngk's, or denso plugs; they're chaeaper, and they seem to have the same, or better performance than the Bosch +4's.

Just say NO!! to Bosch. Stick with what the manual calls out, can't go wrong.

I got my NGK iridiums at a small shop in town here for $6 a piece...not a bad deal and alot cheaper then densos...good plug too just don't shock yourself, it kinda hurts

I was given a set of bosch +4's for my wifes suburban from the rep. Let me tell you that from research I've done and personal experience bosch plugs are KRAP, worse fuel MPG, eratic idle, misfires, pinging ect! I left them in for 1000k miles just to do it, they got progressively worse! Unless you are needing a colder or hotter range plug (superchargers, turbos ect), stick with what it came with. OE plugs are inexpensive and just work like they are supposed to!

For good prices on spark plugs and wires and a few other things for anyone interested try clubplug.net. When I bought my Denso Iridium plugs they were the least expensive of anyone at that time .
