Ignition Coils Compatible with Toyota Highlander
A Highlander that stumbles on a merge usually has a coil boot that has gone soft from heat. These coil and iridium spark plug kits cover select Toyota Highlander applications from 2001-2021. The 2001-2007 years have both a 2.4L listing and a combined 3.0L and 3.3L listing. The two 3.5L bands are not the same kit. Pair the job with cold air intakes compatible with Toyota or a performance tune for Toyota. See ignition parts for Toyota.

Frequently Asked Questions
Which Highlander years and engines are covered?
Select applications from 2001-2021, not every Highlander. Listings are 2.4L (2001-2007), 3.0L and 3.3L together (2001-2007), 3.3L (2008-2010), 2.7L I4 (2009-2019), 3.5L V6 (2008-2016), 3.5L (2017-2019), and 2.5L (2020-2021). The 2008-2010 3.3L kit is not the 2001-2007 3.0L and 3.3L kit. A 2.4L kit is not the 3.5L part. No hybrid displacement is named on these titles.
Will new Highlander coils clear a misfire?
Often, when the cause is weak spark. P0300 means the misfire is moving between cylinders. A single-cylinder code points at one hole. The 2008-2016 3.5L V6 can show codes through P0306. The 2017-2019 3.5L listing does not say V6, so do not assume it is the same kit. Coils and plugs fix the spark side only.
Why do these Highlander listings include iridium plugs?
Every Highlander title in this set names iridium spark plugs with the coils. A worn plug raises the load on the coil. Installing the matched set keeps the gap and the coil on the same job. There is no coil-only Highlander listing here. Confirm the year, because 2001-2007 has two different engine kits.
