Hmmm... I've always used the CRC MAF Cleaner, but I just read the bottle, and it says don't use on "most Lexus vehicles". There doesn't seem anything wrong with my MAF, just wanted to do some preventative maintenance, so not sure if I should risk using this.

Thanks,

 

If it says most i wouldn't risk it

 

I've used it at least 10 times on my is350....no problems at all.

 

I didn't know we needed a MAF cleaner ~

But if it says not to use it, why would you? It might have consequences that sloooooowly show up.

 

those maf cleaners only work on "hotwire" type maf sensors. Find you what kind you have and you should be good.
