The cooler is made entirely from aluminium, eliminating problems associated with cracking plastic end tanks, failures at high boost pressure and leaks between the core and end tanks caused by seal failure. The end tanks are made from precisely laser-cut sheet metal panels and hand-welded using the TIG process for maximum strength and durability.<\/p>\n<p>Solidworks CAD was used during development, along with CFD (computational fluid dynamics) analysis and optimisation. Three different core designs were assessed during development. The final bar-and-plate design outperformed the other two options. The cooler uses a four-pass design, in which the water flows through four passes, improving cooling efficiency.<\/p>\n<p>The Forge system for the BMW M3\/M4 S55, which also fits the M2 Competition F22 from model year 2018 onwards, uses an expansion tank instead of the original collection tank. The filler cap is positioned at the highest point of the cooler, ensuring that the system can be 100% filled with coolant without air pockets. This increases the efficiency of transferring heat from the coolant in the chargecooler\u2019s water jacket.<\/p>\n<p>The existing original rubber mounts are used for the expansion tank and chargecooler, isolating the system from strong engine vibrations. <strong>No cutting or vehicle modification is required, and all parts can be returned to standard condition if required.<\/strong><\/p>\n<h3>The kit includes:<\/h3>\n<ul>\n<li>1 \u00d7 chargecooler<\/li>\n<li>1 \u00d7 expansion tank with sight glass<\/li>\n<li>1 \u00d7 expansion tank cap<\/li>\n<li>1 \u00d7 small cooler cap<\/li>\n<li>1 \u00d7 aluminium cooler cap cover<\/li>\n<li>1 \u00d7 aluminium blanking cap<\/li>\n<li>1 \u00d7 1\/8 NPT adjustment screw<\/li>\n<li>7 \u00d7 M6 \u00d7 12 mm Allen bolts<\/li>\n<li>7 \u00d7 6 mm washers<\/li>\n<li>1 \u00d7 M8 \u00d7 20 mm Allen bolt<\/li>\n<li>1 \u00d7 8 mm washer<\/li>\n<li>1 \u00d7 self-locking M8 nut<\/li>\n<li>3 \u00d7 hose clamps for 8\u201316 mm hoses<\/li>\n<li>1 \u00d7 vacuum hose with an internal diameter of 8 mm and a length of 170 mm<\/li>\n<li>1 \u00d7 vacuum hose with an internal diameter of 8 mm and a length of 750 mm<\/li>\n<\/ul>\n<p><strong>Suitable for:<\/strong> BMW 4 I (F32\/F33\/F36\/F82\/F83), BMW M2 I (F22\/F23\/F45\/F46\/F87), BMW M3 VI (F30\/F31\/F34\/F80).<\/p>\n<h3>Compatible vehicles (manufacturer data)<\/h3>\n<table class=\"tc-fitment-table\">\n<thead>\n<tr>\n<th>Vehicle<\/th>\n<th>Chassis<\/th>\n<th>Years<\/th>\n<th>Engine<\/th>\n<\/tr>\n<\/thead>\n<tbody>\n<tr>\n<td>BMW 2 Series<\/td>\n<td>F87<\/td>\n<td>2017<\/td>\n<td>M2 Competition 2017 (S55)<\/td>\n<\/tr>\n<tr>\n<td>BMW M3<\/td>\n<td>F80<\/td>\n<td>2014\u20132018<\/td>\n<td>F80 4Dr saloon (S55)<\/td>\n<\/tr>\n<tr>\n<td>BMW M4<\/td>\n<td>F82\/F83<\/td>\n<td>2014\u20132020<\/td>\n<td>F82\/F83 2Dr Coupe\/Convertible (S55)<\/td>\n<\/tr>\n<\/tbody>\n<\/table>\n<p><em>Before ordering, check that the product matches your vehicle (model, year and engine).
