I see that denso has several It16,IT20 andIT22's out there what is the difference the number makes??

 

I got the IT22's from JL so I assume those would be the ones to get. I don't know what the diff. is between the others though

 

16-20-22 are heat ranges

16 is hottest

i got the 22's from JL also. best 90 bucks i ever spent!

 

Thats why I asked ,I put mine in monday from JL too and thats when I noticed the I22 on them,that was the first time I heard that number it was usually always IT20's but I guess he wants even a step cooler which is fine by me. thanks guys
