i have a 2001 camry 4 cylinder.
the mtce manual says change spark plugs every 60000 miles
(saying reqd for emission warranty). how often do we have to
change spark plugs and wires.

i see people here are going with iridium plugs. are platinum ones good enough (from dealer)? will the gaps be adjusted if we get it from dealer. do i have to just put it in?

if it says every 60k miles then every 60k miles. from what i've read, upgraded wires and spark plugs won't do much for a naturally aspirated inline 4 engine. it'll help if you're running forced induction or maybe if you set the compression ratio higher

Yes, yes, and yes.

You might want to double check the gap though.

I used the 4 electrode Bosch platinum 4 in my 4 cyclinder Camry and it made a big difference in performance.

i have heard those will fuck up themselves or the engine, i think those are mainly used for racing and more high powered engines than camrys.

i have those bosch +4 platinums, i didn't notice anything

I have 35000+ trouble free miles on them. They're actually listed as a recommended plug for the 4 cyl Camry in the Bosch plug selection catalog.

What about in a V6 Camry? I know it ain't exactly "performance" vehicle, but what would be the best spark plug to use in the 3vz-fe? btw, it's stock....no mods

Whenever you upgrade in power, you want to upgrade all three areas equally, air/fuel/spark.

Stock engine-->Stock plugs are good enough. You will not notice a difference if you just change the plugs.

If I want to replace my plugs, Do I have to replace them with OEM Denso plugs for the car's warranty to be honoured?
I'm thinking of using NGK IX's

I recently replaced my stock spark plugs with Denso IK-20 Iridium plugs...

Mine is a V6 1998 Camry... It does accelerate a little bit better and the RPM's are much stable...
