Which spark plugs should I get?

[Twitchy DSM]

I'm looking to replace my old spark plugs with some newer NGK plugs, which brings up the question; should I go with the BKR6E (stock temp.) or BKR5E-11 (one range hotter)?

The car has a stock motor but has the basic n/t upgrades (including lower resistance coil wires). I hear the one ranger hotter plugs are good for short trips, the car usually doesn't get driven very far but it DOES get driven very often, and usually is driven hard. Would it be a wise choice to get the BKR6E's in that case?

Also, should I have to gap them or are they set from the get-go?


Thanks!

NGK BKR-6, gapped to .045 for stockish daily driver.

NGK BKR6ES gapped at .048-.052.

I doubt you will really be able to make use of the hotter plugs, but at ~$2.50 each you could buy both sets.

Edit: You WILL have to gap them. Usually only the more expensive plugs come pre-gapped.

Go with stock plugs

Stock plugs unless you're going forced induction / nitrous

It's a good idea to gap any plugs, even the "pre-gapped" ones.
