I plan on ordering the jb4 soon.. I know I NEED new spark plugs before installing but are there any other parts that I MUST HAVE before installing the jb4 or can things like occ intercooler and intake be installed later?
Thanks
 
Get new plugs first.
 
Hey SneakerB,

Besides the spark plugs and JB4 unit itself you do not need any other modifications.

I would highly suggest the Wireless Bluetooth Mobile Connect that is offered in the kit as well.

We have a full package with the HKS Spark Plugs and Wireless Bluetooth Connect option on our website HERE.

Feel free to reach out in a message at any time if you ever have any additional questions!
 
The true only must have for a JB4 is plugs. Everything else can come later. :)
Technically you can do JB4 first, just keep it in map 0 (stock) and don't try any other maps until the plugs are done.
The danger is that it may be too tempting to stay in map 0 :)
