http://www.ebay.com.au/itm/PERFORMAN...ht_5039wt_1047
im just not sure if i should get the 25 mm or 12? ive got a 6 cyl 2003 vy executive, what are your thoughts?![]()
The 25mm plenum spacer is best used with forced induction i believe. I have both the 12mm plenum spacer and 25mm manifold insulator, they do a good job (over stock anyway). Ask Steve through the MACE link on this forum he will be able to help you out.
