DIY video demonstrating how to replace the spark plugs in your 2nd generation Lexus IS 250 with the 2.5 liter V6 engine.

Spark plug brand recommendations are either Denso or NGK double laser iridium plugs.
Model years covered are 2005 – 2015.
Car in video is a 2008 Lexus IS250 AWD edition.

3/8″ ratchet driver
1/4″ ratchet driver

awesome video and easy guideline to follow.
thanks for uploading helpful video!.
AWESOME guide. Weekend project here I come! Thanks!
Great video- I'm working on my 2010 IS 250. Having trouble loosening the 10mm on time 3.24. It's too tight and its in an awkward place. Any suggestions?
What tool did you use to get the last 12mm bolt in the back out?
Im surprised hm work this took, my 2008 c300 is much easier to work on.
This is an awesome video! Looking forward to more Lexus is250 videos! Thanks for taking the time man!

Nice, i need to do mine. As well as the valve cover gaskets. Wish me luck
Great, detailed video tutorial!!

This is a very well demonstrated DIY….I will be using it to replace my spark plugs soon. Thank you!
thanks for the video. I just changed my spark plugs in my 2010 is250 and I discovered that the "bitch" bolt is not part of the design
holy fucking crap. that 12 mm bolt in the back was a pain in the ASS. it is useless and doesn't hold anything. well it does the intake manifold but really useless. bloody knuckle and I didn't even put it back. lol
Thanks for sharing the great video. Very informative.
Thank you taking the time to make a video for this process!
