I have a 2005 VZ SV6 with the Alloytec 190 engine it lacks off the mark acceleration etc it’s been fitted with a 2.5" catback exhaust system and extractors. What do I need to get that extra power of the mark and throughout the rev range? Also I don't want

The cold air intake and manifold insulator will definitely increase low end torque and power throughout the low to mid rev range. The harmonic balancer kit will reduce parasitic engine power losses from driving accessories. Cold Air Intake kit-$270 Manifold insulators;-12mm-$150 25mm-$220 Underdrive Harmonic balancer kit-$292 Total Price: $782 (25mm manifold insulator) plus $45 postage. However if you buy this package we wont charge you for postage.
