{"title":"BMW 135is Parts and Accessories","description":"\u003cp\u003eThe BMW 135is is the top-spec variant of the E82 coupe, featuring the N55HP engine with higher output from the factory, active M differential, and additional chassis and interior enhancements that set it apart from the standard 135i. It is a rare and well-equipped base for performance tuning.\u003c\/p\u003e\n\u003ch4\u003ePopular Upgrades\u003c\/h4\u003e\n\u003cp\u003eExhaust upgrades — particularly cat-back systems and downpipes — are among the first mods on the 135is, where the stock exhaust is conservative given the car's performance character. Coilovers and sway bar upgrades work especially well on the 135is given its M differential, allowing the rear to rotate more confidently under power with better chassis control. Cold air intakes improve throttle response and complement the N55HP at higher boost levels.\u003c\/p\u003e\n\u003ch4\u003eHow is the 135is different from the regular 135i?\u003c\/h4\u003e\n\u003cp\u003eThe 135is uses the N55HP engine, which produces 320 hp versus the standard 135i's 300 hp, and adds an active M limited slip differential, a DCT transmission option, and a more aggressive factory suspension tune. These additions make the 135is a stronger starting point for performance builds and a closer match to the 1M in overall capability.\u003c\/p\u003e\n\u003ch4\u003eWhat tune options are available for the N55HP in the 135is?\u003c\/h4\u003e\n\u003cp\u003eThe N55HP in the 135is responds well to ECU stage 1 and stage 2 tunes from BMW-specialist tuners. Supporting bolt-ons — downpipe, intake, and intercooler — carry the 135is into the 380–420 hp range on a stage 2 map, a significant improvement over the factory output.\u003c\/p\u003e\n\u003cp\u003eUpgrade your BMW 135is with parts from our \u003ca href=\"\/en-ca\/collections\/exhaust\"\u003eexhaust systems\u003c\/a\u003e, \u003ca href=\"\/en-ca\/collections\/suspension\"\u003esuspension upgrades\u003c\/a\u003e, and \u003ca href=\"\/en-ca\/collections\/air-intake-systems\"\u003ecold air intakes\u003c\/a\u003e collections.\u003c\/p\u003e\n\u003cscript type=\"application\/ld+json\"\u003e\n{\"@context\":\"https:\/\/schema.org\",\"@type\":\"CollectionPage\",\"name\":\"BMW 135is Parts \u0026 Accessories\",\"description\":\"Shop BMW 135is exhaust systems, suspension upgrades, and intakes for the N55HP engine with fast shipping.\",\"url\":\"https:\/\/www.blackopsautoworks.com\/collections\/bmw-135is-parts-and-accessories\",\"breadcrumb\":{\"@type\":\"BreadcrumbList\",\"itemListElement\":[{\"@type\":\"ListItem\",\"position\":1,\"name\":\"Home\",\"item\":\"https:\/\/www.blackopsautoworks.com\"},{\"@type\":\"ListItem\",\"position\":2,\"name\":\"BMW 135is Parts \u0026 Accessories\",\"item\":\"https:\/\/www.blackopsautoworks.com\/collections\/bmw-135is-parts-and-accessories\"}]},\"potentialAction\":{\"@type\":\"SearchAction\",\"target\":\"https:\/\/www.blackopsautoworks.com\/search?q={search_term_string}\",\"query-input\":\"required name=search_term_string\"}}\n\u003c\/script\u003e\n\u003cscript type=\"application\/ld+json\"\u003e\n{\"@context\":\"https:\/\/schema.org\",\"@type\":\"ItemList\",\"name\":\"BMW 135is Parts \u0026 Accessories — Top Categories\",\"description\":\"Aftermarket parts for BMW 135is\",\"url\":\"https:\/\/www.blackopsautoworks.com\/collections\/bmw-135is-parts-and-accessories\",\"itemListElement\":[{\"@type\":\"ListItem\",\"position\":1,\"name\":\"Exhaust Systems\",\"url\":\"https:\/\/www.blackopsautoworks.com\/collections\/exhaust\"},{\"@type\":\"ListItem\",\"position\":2,\"name\":\"Suspension Upgrades\",\"url\":\"https:\/\/www.blackopsautoworks.com\/collections\/suspension\"},{\"@type\":\"ListItem\",\"position\":3,\"name\":\"Cold Air Intakes\",\"url\":\"https:\/\/www.blackopsautoworks.com\/collections\/air-intake-systems\"}]}\n\u003c\/script\u003e\n\u003cscript type=\"application\/ld+json\"\u003e\n{\"@context\":\"https:\/\/schema.org\",\"@type\":\"FAQPage\",\"mainEntity\":[{\"@type\":\"Question\",\"name\":\"How is the 135is different from the regular 135i?\",\"acceptedAnswer\":{\"@type\":\"Answer\",\"text\":\"The 135is uses the N55HP engine, which produces 320 hp versus the standard 135i's 300 hp, and adds an active M limited slip differential, a DCT transmission option, and a more aggressive factory suspension tune.\"}},{\"@type\":\"Question\",\"name\":\"What tune options are available for the N55HP in the 135is?\",\"acceptedAnswer\":{\"@type\":\"Answer\",\"text\":\"The N55HP in the 135is responds well to ECU stage 1 and stage 2 tunes from BMW-specialist tuners.
