Anyone know where the cheapest place to buy these from?

 

Try summitracing.com they probably dont have it listed in their catalogs or website but can order them for you if you get them a part #. free fast shipping also.

 

Anyone else?

Just ordered from here, cheapest that I could find

https://www.rockauto.com/dbphp/prt,100,3857

 

http://www.monarchproductsinc.com/, not sure they are any cheaper than what you already found.

 

In your title you stated you wanted the 11.5 heat range, and that link that you ordered from it was the 10.5 ones at 25 bucks...the 11.5's are like 31 from that place..the cheapest you will find the 11.5 are from www.rx7.com at 28 and some change.

 

Yes I know, I decided to go with 10.5's

 

Cool, thats what I am running, and in that case, that is the cheapest

 

It's weird that Ari sells the 10.5 and 11.5 plug for the same price......

 

I know I was wondering why that was too, maybe he figures it will be a wash since I assume most buy the 10.5's at a little higher price (3 bucks more than the other place) and sell the more expensive 11.5 for a little less (3 bucks less)but less people buy them, so the profit margin is higher for the 10.5's
