Q4: How much horsepower will I gain?

A4: EGR delete alone may offer small gains (0-5 HP), but the real benefits come from improved throttle response, better airflow, and engine longevity.

Q5: Does this kit void my factory warranty?

A5: Yes, installing any emissions-delete product may void your original equipment manufacturer (OEM) powertrain warranty. Please consult your dealer.

Q6: What’s included in the kit?

A6: EGR delete plates, high-flow intake pipe, gaskets, mounting hardware, and optional black or blue finish.

Q7: How difficult is the installation?

A7: For experienced DIYers, it’s a moderate-level install. Beginners should seek professional help.

Q8: How long does the installation typically take?

A8: The estimated installation time is around 2 to 4 hours, depending on your mechanical skill level and the tools available.

Q9: Will this kit help lower my EGTs?

A9: Yes, by preventing hot exhaust gases from recirculating into your intake, this kit helps lower Exhaust Gas Temperatures (EGTs), which is highly beneficial when towing or under heavy loads.
