How many of you guys have changed out your stock plugs yourself, and if so was it difficult for a DIY job??

What is the interval that Lexus recommends, and what type are they (NGK, Denso, etc....)?

 

Lexus recommends every 60k miles, as for brand names I would just go w O.E. & have a certified tech install them. They are $125 bucks for a complete set alone.

 

I picked up the OEM Densos from Advance Auto Parts for $90 shipped when they had a promotion going on. I think they run it once or twice a year.

The job itself is pretty straightforward, I would want to kick my own *** if I spent $400 for the dealer to do it. Took me about 3 hours taking my time.

 

I'm at 55k and i would also like to know if anyone has done it. i don't want to spend the labor to have the dealer do it if i can do it. i mean i work on jet engines how hard can it be.

 

I'm at 45k right on my 08.. its been 7 years. Do you guys recommend for me to change it soon?

FYI - I have already purchased a set of spark plugs and sitting my basement for the winter

 

Those jet engines might be affecting your reading skills. As I said in the post directly before yours, it is an easy job.

 

if you have the tools its not that hard to change. Its just hard getting to some of the plugs its PITA.

lots of threads on this....

^^^^Thanks those links were what I was looking for!

 

It took me about 4 hours to do. I can probably do it again in 2. I spent a lot of time trying various tools and attachment combinations to get the plugs in and out. It's very cramped

 

My mechanic spent 2-3 hrs on the job, it was very cramped. He charged me $80 I think it's well worth it

 

115000 miles on my mums GS300 spark plugs. Just changed them.
