Buy memcal or plennum spacer?

[triple b]

Hey

I have a vs commo v6 manual with full exhaust system (extractors, high flow cat, 2.5in pipe) and was wondering which product would be more beneficial, the 12mm plenum spacer or the memcal?

Also if I was to buy the memcal first and then later buy a plenum spacer or manifold spacer would this have any effect on the memcal (i.e. not reaching full potential due to the memcal not being a custom tune)

Thanks guys

I would buy the 12mm spacer. Then buy a custom tune memcall after all the mods. Why dont you get the 25mm one?
longer runners and the right diameter runners can give you more down low power. And shorter runner length give power up in the rev range.

IMO the 12mm manifold spacer would be best to starters.
It will better prep for later mods

Given what you're considering if you can start off with the manifold insulator first it would be better.

As for the memcal, a general rule is to consider investing in one once you've done all of the mods you want to do.

Hope this helps
