    Just installed instant improvement

    11 of 11 people found this helpful

    Just installed these in my 07 Tacoma V6 4.0L and took for a test run. Noticed instant improvement in acceleration. Tapped gas pedal at stop sign to pull out onto main road and felt noticeable increase in response and power. These plugs came pre gapped at .043 which is what the taco manual says, so no need to adjust. The OEM plugs were not iridium which was a surprise so at 90k miles I was way overdue. These iridium plugs are supposed to give a more efficient spark so I should see an improvement in gas mi. If you have a V6 toyota and these plugs fit, I'd say they're def worth the $8.50 ea.

    Pros: Pre gapped, decent price, NGK makes great plugs

    Cons: None
