i need to know on an 2001 lx do the spark plugs have to be tourqued and is there a way to do it. i've been told to tighten them til they are snug is that true someone help..

Yes they need to be torqued. Usually to 15-18ft/lb.

you dont need to torque them, I just snuged them up.

yea.. you gotta torque them.. otherwise they will start loosening.. and eventually fly out the threads and cause some damage

this is funny it is an argument does any one really know for sure lol

I think that is EXTREMELY rare... Ok that just will never happen.
The plugs have like 1" of threads on them, They are not going to loosing out that much.

I've alway's snugged them like a drain plug and have never had a problem.

I thought it was 13 foot pounds?

yea im sure that wont really happen with the 01+ civics, but my buddy who has a 97 had his spark plug boot destroyed and it shot up and made a reverse dent in his hood

as easy as it is to troque it down, i would rather do that than risk any possible damage no matter how remote the possibility may be.

with the spark plugs, once it gets tight, turn it a tad more and thats it.

does anyone know where i can buy some spark plugs? for 03 ex

screw them down by hand then 1/4 turn and ur good...take it from some1 in the field and not a ricer

I would highly recommend a torque wrench. The plugs are supposed to be a certain distance, so it's important. And I believe it's 13 ft/lbs you want.

Indeed it is.
Doesn't anyone look at the owners manual?

and how many spark plugs do we have to change?

LOL, what kind of question is that !! HAHA

See, some of us say to torque them, others say that you dont need to.

I can honestly say that just tighten them a bit more than the usual and your good to go. Its really not that big a deal...others are a bit **** about it, but, if you want to torque them...torque them. If you dont want to, then dont. Its really not needed.

lol i have no idea bout this topic dont hate jus give me an answer lol

4 FOUR! As in 4 cylinder engine.

Yes you NEED to torque them. Too loose the engine will overheat, too tight and they won't come out next time. Take your chances if you want.

hahah !!!!!!

Some cars have four cylinders and more than four plugs.

Yeah Nissans had 8 plugs for their 4 cyl engines,,

truck engines

But civic isn't a truck, it's a car.

Torque by definition is a twisting force. So if you are attaching any fastener such as a screw, bolt, or a nut, you are applying torque. Whether it is with your fingers, or a wrench, you apply torque. I believe what everybody is asking is if it needs to be torqued to a specific value. In this case, you would need a torque wrench to measure this torque.

Duhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhh hhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhh hhhhhhhhhhhhhhhhhhhhhhhhhhhhhh

I had a Nissan Stanza, which is a car (an Altima before there were Altimas if you will). It had a 2.0L 4 banger... it had 8 spark plugs.

Here's what NGK's website says:


"Torque is one of the most critical aspects of spark plug installation. Torque directly affects the spark plugs' ability to transfer heat out of the combustion chamber. A spark plug that is under-torqued will not be fully seated on the cylinder head, hence heat transfer will be slowed. This will tend to elevate combustion chamber temperatures to unsafe levels, and pre-ignition and detonation will usually follow. Serious engine damage is not far behind. An over-torqued spark plug can suffer from severe stress to the Metal Shell which in turn can distort the spark plug's inner gas seals or even cause a hairline fracture to the spark plug's insulator...in either case, heat transfer can again be slowed and the above mentioned conditions can occur. The spark plug holes must always be cleaned prior to installation, otherwise you may be torquing against dirt or debris and the spark plug may actually end up under-torqued, even though your torque wrench says otherwise. Of course, you should only install spark plugs in a cool engine, because metal expands when its hot and installation may prove difficult. Proper torque specs for both aluminum and cast iron cylinder heads are listed below."


According to NGK's chart, stock 1.7L Civics have 14 mm thread diameters, so they should be torqued to 18.0~21.6 lb-ft.

That's correct except the torque is 13ft/lbs per the service manual from honda.
