Hey everyone its Erik from MAPerformance.com. Today we are going to check out this 4G63 Beehive Valve Spring Kit from us at MAPerformance.
MAP beehive valve springs are engineered to exacting tolerances utilizing only the finest materials by an ISO certified valve spring manufacturer. These springs directly compare to other leading manufactures products and come in at around half the price! Designed with performance in mind these valve springs are ideal for camshafts that feature more aggressive lift and duration profiles.
So what is a Beehive Valve Spring? And why should you get it over a single, double, triple or other type of spring?
MAP beehive valve springs utilize ovate shaped wire that more effectively distributes stress over the entire wire area in comparison to a typical round wire spring. The thinner cross-section wire also allows for more coil bind clearance to accommodate higher lift camshafts. Retainer end mass is reduced allowing for improved performance in high RPM applications and coil surging is dramatically reduced providing improved valve control and fatigue life of the spring itself.
This particular kit includes a complete set of 16 valve springs that are designed to utilize your factory Evolution 8 & 9 spring seats and retainers. If valve train stability is your primary concern, replacing your factory springs with these alone is more than sufficient for the majority of our customers. However, a complete kit with titanium retainers at an additional cost would further reduce valve train mass if that is the intent.
Please Note: These springs will work ONLY with the stock Evo 8/9 retainers or MAP Titanium Retainers. Other stock 4G63 retainers (including Evo 7) are NOT compatible with these springs. If you need a set of springs with retainers, please purchase our Beehive Spring Kit with Titanium Retainers, a link can be found in the description.
