The right OEM Exhaust Manifold Gasket 17173\u201121020 could be the solution.<\/p>\n<p>It\u2019s the factory-grade gasket sealing the exhaust manifold to the cylinder head on many Toyota and Scion 1.5\u202fL models from 2000\u20132019, engineered to prevent leaks and ensure optimal engine performance.<\/p>\n<p><img decoding=\"async\" src=\"http:\/\/hengoseal.com\/wp-content\/uploads\/2025\/06\/17173-21020-exhaust-pipe-gasket.png\" alt=\"placeholder_image\" \/><\/p>\n<p>Let\u2019s explore five real Google PPA questions people ask about this part, so you can find precise answers and make informed decisions.<\/p>\n<h2>What vehicles does part 17173\u201121020 fit?<\/h2>\n<p>Curious if your car is compatible with this gasket?<\/p>\n<p>It fits Toyota Yaris, Prius, Prius C, Echo, and Scion xA\/xB with 1.5\u202fL NZ-series engines produced between 2000\u20132019.<\/p>\n<h3>Why is fitment accuracy important?<\/h3>\n<p>Using an incompatible gasket causes exhaust leaks, misalignment, and engine inefficiency. Always verify via VIN or vehicle picker on OEM parts sites.<\/p>\n<h2>How much does the OEM gasket cost?<\/h2>\n<p>Looking for the price before ordering?<\/p>\n<p>At Hengoseal, we offer direct factory pricing\u2014under $1 per unit\u2014for the OEM 17173\u201121020 Exhaust Manifold Gasket, making it one of the most cost-effective solutions on the market.<\/p>\n<h3>Is the price worth it?<\/h3>\n<p>Absolutely.

This is unbeatable compared to $17\u2013$27 listings on other platforms.<\/p>\n<h2>Is it better than aftermarket alternatives?<\/h2>\n<p>Should you risk performance with cheaper options?<\/p>\n<p>Genuine Toyota OEM-spec parts like the 17173\u201121020 gasket ensure precise tolerances, multi-layer steel construction, and durability that many aftermarket versions lack.<\/p>\n<h3>What can go wrong with aftermarket?<\/h3>\n<p>Cheaper gaskets often warp or fail under heat.
