Why do you have to gap them to spec? Dont they get supplied gapped to spec? My new plugs were delivered as per the spec.
Sure you have the right plugs or spec? |

I been doing plugs and such for a long time, bikes and cars. NEVER trust the factory gap. Things settle in shipping and bump around, and can knock them out of spec.
It's just good to be sure. |
When you gap plugs, what are you doing exactly? I have come to the assumption that the center electrode is stationary, and you are bending the ground electrode closer/farther from it. Is this correct?
If so, I would suspect that the pre-gapping is quite accurate. I just did my plugs and they were all set darn-close to the 0.7mm spec. My old plugs had the center electrode worn down to a ~1mm gap, though... So, can you extend the life of a plug by pulling it out part-way through its life and bending the ground electrode in to shorten the gap?

Hi, this weekend i went home to switch out my winter tires as one of them blew out this past weekend due to a nasty pot hole and i was riding on the doughnut. So when i got home i decided to put some new parts on seeing it would only take me an hour or so. So i went home put on my new All seaons, Eagle Gts, replaced the oil with Mobil One, changed out the fuel filter and put in new plugs. The weird thing was, i was getting around 30MPG on the way home and on the way back i was only getting 20 or less. Ive been driving it for a while, probably 400 miles since the new parts and still getting very horrible gas mileage. Any thoughts? Power is still where it should be for a T5 and dont notice anything different than before.
Any ideas would be great,
thanks a bunch |
I just got my snows replaced with all-seasons a month ago and didn't notice any large drops/jumps in gas mileage. Although, 35 psi sounds a bit high for winter tires. Maybe your all-seasons are much too low?
And I just did my fuel filter and spark plugs (also from IPD) this last weekend, but I haven't driven enough to check mileage. Oil will be done soon... Will see if I have any severe drop in gas mileage, too!

ya, well when i get home in 3 weeks ill update and let you guys know what the issue was. It sucks having a tire iron as your only tool! |
Live near a Harbor Freight? Get yourself a $20 torque wrench to get you through college
(Having one is better than nothing!)
How about a Sears? I've got
this set of tools. Comes in a handy-dandy carrying case and has a good variety of US and metric sockets and wrenches as well as a
very good spread of torx screwdriver bits http://********************/smile/emthup.gif (You'll just need to get some sort of extension to get spark plugs in/out, but that shouldn't be a problem as you'll need a spark plug socket anyway!)
Here's a thought: maybe you didn't tighten your turbo charge pipe correctly after replacing your spark plugs? This was the first time I had done plugs on a turbo car and that stupid pipe was such a PITA! (Well, not really... Just one more thing to learn about how to get around... And it's worth having it the rest of the time!
)
