PART NUMBER: 61-3194
HPS high temperature 4-ply reinforced silicone air intake hose kit replaces 2006-2008 MX5 stock OEM rubber restrictive air intake hose with high-heat resistance material which meets or exceeds OE specifications (Maximum temperature rating: 350F). Without any re-tuning, the HPS silicone air intake kit improves air flow, better throttle response and driveability. HPS silicone intake kit also helps to reduce heat soak. Tuning and modification are not required.
Besides performance gains, HPS silicone air intake hose kit is the perfect replacement part to prevent or fix the bad idling and air vacuum leak issue commonly caused by cracked, damaged or collapsed OEM rubber air injection hose.
Brian asked for a review, so here it is. This is a nice looking piece that smooths out the airflow into the throttle body. As for any performance gains I don't know. You would have to put your car on a dyno and do a before and after test.
