2007 RAV4 Sport 4 Cylinder

Can someone give me some idea of how difficult it is to replace the spark plugs in my vehicle? I would have a fairly experienced do-it-yourselfer helping me but he has never worked on a RAV4 before.

Platinum plugs seem to be cheaper but the manual says to use iridium. I would like to follow the manual's recommendation if it is reasonable - not just a way to get me to buy OEM plugs from Toyota.

How to replace sparkplugs?

This is one topic that I have not seeing here yet. It would be nice to see someone post pics of spark plug replacement.

C'mon dude they are Super, duper easy on a 4cyl. Just take off the plastic cover, pull up the coils and unscrew the plugs. Then do the reverse. You should be done in 15 minutes if you take your own sweet time about it. The 6cyl on the other hand is a bit more trouble because of the front wheel drive design and the intake covering the rear plugs. You don't have to worry about any of that though.

I don't have the 4 cyl RAV4, but here is a thread for a Tundra/Sequoia that should help you get started.

Spark Plug replacement HOW-TO w/ pictures

If you buy NGK plugs, you won't have to use anti-seize. Make sure the iridium plugs are pre-gapped correctly before you buy them at the store. Your owners manual should give you the proper gap and torque settings. If you try to gap them yourself when you get home, you may damage the iridium tip.

I like the magnetic spark plug socket over the rubber insert type. Make sure that you use electrical tape to keep the 6" extension attached to the socket. You don't want to leave the socket down in the hole when you try to remove it when you're done!

Good luck, take your time, and have fun. It's really not very difficult, unless you make it be.

First off the iridium plugs last in excess of 100,000 miles so are you sure they need replacing? If so, using anything other than the correct iridium plug would be a foolish mistake. If you can unscrew a light bulb you can change the spark plugs.

I have had that happen to me countless times. What I do is just insert a set of long needle nose pliers and pull the socket back out. Not a big deal really.

The only area of caution that I would advise is to use a torque wrench to install the new plugs into the head, which is aluminum. I've seen newbies bear down too hard and strip out the spark plug hole threads. You have to be pretty brutal to cause this to happen. If it does happen though, you have a world of hurt.

Rav408 is right easy job. just take your time Buy the iridium plugs because the the load they put on your coils are low.replaced mine at 70,000 miles and they looked good . I think at 120,000 they would have been fine.platnums would work but your coils could fail one by one and they are not cheap.

IMO, there is no reason as all to not consider putting in double platinum plugs on a 4 cyl. You just need to do the math and decide if it is worth the extra savings. You will likely get 60-80K out of double plat plugs vs. 100-120K from iridium. If you plan on keeping the car, maybe iridium is you choice. But, you do have other choices.

I have changed dozens of spark plugs without torque wrench, even on aluminum blocks. Just don't have to go crazy tight. All you need is the plug to be snug.
Yea, this is true. I would go one step further. I was taught to always introduce the plugs into the block by hand. You can't do that on blocks where the plugs are deep inside like these, so what I do is insert the plug into the extension, and simply use the extension as an extension of my hand. Thread it into the block with your hand, NOT the ratchet. Once the plug sits nicely, then you attache the ratchet and tighten snug if you don't have a torque wrench. Just tight enough, but not very tight.

How many miles to you have on your 2007 RAV4 Sport 4 Cylinder?
I have 115,000 miles. I am trying to do everything that I can do myself for the 120,000 mile service per the service recommendations in the manual.

I've already done oil/filter, air filter and cabin air filter.

plugs on my 2007 RAV4 4 cylinder were replaced at 130,000 miles and these original iridium plugs had normal wear, even with the engine burning excessive oil.
