spark plug recommendations?

[fondoo]

my 2003 camry is getting close to 100K miles now and what spark plugs do you recommend? should i just buy toyota dealer spark plugs? are they easy to replace?

NGK that fit your engine, not sure if you have a 4 cyl or 6cyl

Platinum would work, I would go with Iridium myself.


4cyl

NGK Part # 2978 {Premium Platinum #BKR6EP11}
DOHC {.044 gap}


NGK Part # 4589 {Premium Iridium #IFR6T11}
DOHC {.044 gap}


6 cyl

NGK Part # 2978 {Premium Platinum #BKR6EP11}

NGK Part # 4589 {Premium Iridium #IFR6T11}
DOHC {.044 gap}

Updated model - but the old part numbers I had up there would work just fine

Here is the chart to look them up yourself

The stock plugs in the I4 are NGK Laser Iridium or Denso Long Life Iridium and should have longer life than the IX Iridium and GP Platinum.

The stock plugs have platinum or iridium chips on both the center and side electrodes; kenny's recommendations do not.

Assuming you have an I4 engine, they are easy to get to. Pull the plug wire cap off one plug, use a 5/8 (I think) deep well plug socket, a 6 inch extension, and a ratchet. Pull one plug out, jot down the number, and replace until you get a new set. Do this when the engine is cold, and it doesn't hurt to put a drop of light oil on the plug thread before reinstalling so that it goes in easily and doesn't booger the threads.

I second the recommendation for NGK Laser Iridium.

Depends on price, there is no reason to pay the toyota markup for plugs, toyota doesn't make plugs so the NGK is the same plug for possibly less money depending on your dealer pricing.

rockauto.com sells the NGK Part # 4589 for $6.80 each + shipping. My local toyota dealer is a theif and charges OVER msrp for parts like this. So there might be a reason not to buy them from a Toyota dealer directly YMMV

Same plugs as the 03. You have the same 2AZ-FE engine. From my experience the best plugs are the NGK Laser Iridium.

Leave them alone. The maintenance interval 120 thousand miles.

The plugs have platinum chip on the side and iridium chip/ring on the center electrodes. This makes the service life longer by detering electrode erosion.

At 60k, the only thing I'd do is change the two air filters and optionally drain and refill transmission and radiator. Do not flush the cooling system since you can only buy the Toyota coolant in diluted form. If you change to something like Peak Global coolant, that is different though.

Sorry, close but no cigar. The 2.4 liter starting in 2002 has a coil on plug design. Start by taking off the top engine cover. Working on 1 cylinder at a time, remove the wire connector from the coil and the bolt holding the coil to the valve cover. Pull coil straight up and off. From there its just a simple matter to remove and replace the plug. Do not touch the gap on Iridium plugs, they are factory set and do not need to be adjusted. NGK or Denso plugs would be the only two brands I would even consider putting in a Toyota. While you have the top engine cover off I would replace the pcv valve. It screws into the rear half of the valve cover on the passengers side. Good luck to you sir.
