What is the spark plug gap for a 3.5 EcoBoost?
| Engine 3.5L EcoBoost | Firing order 1-4-2-5-3-6 | Ignition system Coil on plug | Spark plug gap 0.030–0.033 in (.75–.85 mm) | Compression ratio 10.0:1 |
|---|
What is the spark plug gap for a Ford?
Proper Gap
054 inch
. This gap is checked by placing a feeler gauge or a spark plug gapping tool between the two electrodes. If the spark plug is . 002 inch or more too wide or narrow, slightly pry upward or push downward on the ground electrode to adjust the gap.
What is the correct reading for spark plug gap?
The gap setting is different for each vehicle but most are somewhere
between 0.028′′ and . 060′′
. Consult the owner’s manual or Champion
®
catalog to find the recommended setting for the vehicle you’re working on.
What is better platinum or iridium spark plugs?
Iridium
is said to be six times harder and eight times stronger than platinum with a 700° higher melting point. Iridium spark plugs have extremely fine electrodes while retaining excellent wear characteristics. Thanks to its strength, iridium spark plugs can last up to 25% longer than comparable platinum spark plugs.
What company makes Motorcraft spark plugs?
“As a division of the Honeywell Corporation,
Autolite
is the manufacturer responsible for the production of all Motorcraft spark plugs in North America for the Ford Motor Company. Both Autolite and Ford/Motorcraft spark plugs are built to quality standards using quality components.
Does 3.5 EcoBoost have spark plugs?
Ford puts a lot of effort into the spark plugs that go into their latest generation of F150 engines, and their
Motorcraft Iridium Spark Plugs
are a surprisingly good choice for the 2011 to 2016 F150s rocking a powerful 3.5L EcoBoost V6.
How much compression should a 3.5 EcoBoost have?
| Engine: Ford 3.5L EcoBoost V-6 | Cylinder Stroke: 3.41′′ (86.6 mm) | Compression Ratio: 10.0 : 1 (2011 – 2016 MY) 10.0 : 1 (2011 – 2019 H.O.) 10.5 : 1 (2017+ MY) | Aspiration: Twin parallel mounted turbochargers, (Borg Warner K03 for truck version, Garrett GT15 for other applications) |

Do Motorcraft spark plugs come pre gapped?
The fine
tip iridium are always pre-gapped at factory
and the manufacturers specifically say that should NOT be messed with by user. The Motorcraft ones are cheap versions of Autolite Dual Platinum, they requested “no factory gapping” to their OEM (Autolite) to save costs, that’s why the gap is never exact.
Do you gap platinum spark plugs?
DENSO spark plugs are manufactured with a pre-set gap. …
Do not change the gap on platinum
, iridium or twin tip spark plugs, as the fine electrodes may get damaged.
What is spark plug gap?
The
critical distance between the spark plug’s electrode and the ground strap
(that piece of steel that curves out over the end of the plug) is called the “plug gap.” The act of setting this distance correctly is commonly referred to as “gapping” your plugs.
Does spark plug gap have to be exact?
The gap between the center and side electrodes of a spark plug
must be an exact distance
; otherwise, your plugs don’t fire efficiently. Adjusting the distance between the two electrodes is called gapping your spark plugs. You need a feeler gauge to gap your spark plugs properly.
What happens if spark plug gap is wrong?
Spark plugs that are gapped incorrectly can cause an engine to miss, or run erratically, especially during idle. The incorrect spark plug gaps can
cause uneven firing of individual spark plugs and delay engine combustion
; both of which can cause an engine to miss or idle erratically.
Is a wider spark plug gap better?
The
larger the gap
, the more voltage is needed to jump the gap. Most experienced tuners know that increasing the gap size increases the spark area exposed to the air-fuel mixture, which maximizes burn efficiency.
