MTC Motorsport Astra VXR GSI SRI MK4 Tophat (to join to MTC Motorsport powerpipe)

• This upgrade bolts on in 5 minutes and is a great modification for the Z20LET 2.0T engines (will not fit to a standard car).
• This tophat will provide sharper throttle response and give you extra power through the rev range, also keeping charge temperatures down.
• The kit is made of a 2.5" tin-walled alloy pipe and finished to a mirror polish. 
• The flange onto the throttlebody has been laser cut out of 8mm alloy and follows the edge of the throttle body perfectly.

• x4 Stainless Bolts
