Watch out for that if it’s on the wrong cylinder for a while it’ll start having affects with your timing. And everyone knows the headaches and how expensive it is to fix the timing on your car.

[@eckosmediaroom]

Doing this now. Thanks for the how to. #props

[@josephpossanza5022]

Getting ready to do this on the weekend. Maybe fuel injectors in a month or so.. Had a weird misfire last week that lasted 5 minutes but no Misfire codes when I put the reader on. Just EVAP system code, so no clue. I need new spark plugs anyways so I figured I'd start here first... I bought the uhhhh spark plugs that are for engines with small mods such as even a cold air intake. So hope it all works out .

[@FrilledNeckDragonUK]

Thanx very much very clear :)

[@B1NO_O]

also i took the hose that connects to the plenum and runs next to the battery back into the fire wall that let air out could that be causing anything?

[@craigponzio236]

Brother, what's the gap ? 0.044? and are ngk 6240 's correct, as well as Hitachi IGC0007 coil pack? Thanks Bro

[@nhikkeyfayloga327]

Bro i have questions i did change my spark plugs but its starts but after its die slowly??help please

Do you have a link to the air intake hose?

[@adammarron3085]

With wat socket I use to torque down the the spark?

[@Sleepyperformance]

Your channel is so underrated, awesome video and tips I would love to see a safely engine bay cleaning video. U probably have a full exhaust but if u don't, what are ur thoughts on installing a walker to replace de resonator? I'm asking cuz I'm thinking on doing it.

[@ERICSDIYGARAGE]

thank you so much! it depends what your going for. now in days you can fine a cheap after full exhaust. if your not into that I dont see a issue with the Walker mid pipe

[@user-up3vx2hk1q]

Those are some crazy spark plugs. Mine where just as bad when I changed them out 😆. Couldn't believe my car ran with them like that too

[@ERICSDIYGARAGE]

Haha I'm glad I'm not the only one

[@bossiesur]

Did it drive better? Lol

[@josefermalino461]

what’s the part number of the spark plugs u using bro? Awesome video I learn a lot

[@ERICSDIYGARAGE]

I'll definitely consider it 🤞

[@kEEPITMOVIN408]

What size is the socket for the spark plugs

[@DopeAFLegion]

Lmao I dead ass be looking for your videos only😂

[@sneakerguy2430]

Guys I changed my new spark plugs with the old ones and they are working well but my exhaust sounds like a rotary,I've switched the coils and it still sounds bad. I have minor oil on three of the passenger side valves but it runs good. Tf do I do

[@Longtrailside]

Well done.

[@ERICSDIYGARAGE]

thank you!

[@andrewagape9244]

Could old spark plugs cause detonation?

[@osamabinpackinjr2813]

So after do we just start the car

[@tomraleigh1924]

Why no anti seize on NGK?

[@audioamateur]

Great video as always. Quick question: do spark plugs get damaged from close proximity with a magnet? I'm asking because of what you mentioned in the video

[@ERICSDIYGARAGE]

thank you so much! The magnet alone should not damage the spark plug, I didn't use it to install the new ones because it's hard to screw the spark with the magnet and I find it easier to use a hose that can grip the spark plug

[@audioamateur]

@@ERICSDIYGARAGE ok thanks for clearing that up. These two vids were perfect because I was already planning to change my spark plugs and also maybe do the valve cover gaskets as well. Do you know if ignition coil performance degrades with time or is it more a matter of replacing them when they die?

[@ERICSDIYGARAGE]

@@audioamateur I'm glad that they will come in handy, from what I've seen people have nothing but issues with they change the coils because they use aftermarket coils that die quickly and eventually go back the the original ones that they were using. I would leave them and if you have misfires or any other issue after replacing the spark plugs than maybe swap them out but if not just leave the original ones

[@B1NO_O]

hey i have a couple of questions for cylinder 4and 6 do the ignition coil wires cross? i put new coilovers and my car has a bad idle to the point my rmps drop lower then 1,000 before the car almost dies i also have a decent sized crack in the pvc pipe u removed when taking the spark plugs out could that be a problem?

[@ERICSDIYGARAGE]

Yes that would make it run rough fix that and you probably did cross the spark plug coil packs

[@stacymitchell1890]

5:15 that's a great trick!

[@SeanLaMontagne]

My 03 g35 is just now burning spark plugs at 183k. I'm not the first owner, but I'm certain they've never been changed before.

[@prestonking7708]

yooo the cut had my dying when putting the first plug in! Great video, thanks! im gonna tackle this week. I saw you had a pivoting wrench and an extension bar to make things easier along with the magnet and tubing. Were there any other specialty tools that helped? I've heard of spark plug sockets that have rubber in them?

[@gstacks510]

Get a socket with a magnet...

[@nicholi8208]

Is dialectric grease not needed? I have to do a 05 g 35 spark plugs and coil pack swap out

[@ERICSDIYGARAGE]

it's not needed

[@christianc1282]

Should get you a magnetic socket they come in handy really good

[@watersnortmoment3734]

They're pretty inexpensive too, usually they can wobble a bit as well. Worked perfectly for my 8th gen si, hopefully I can reuse the same one, the plugs are similar if not the same from what I remember.

[@sorandom1388]

I recently changed my spark plugs but now I have poor idle , I'm getting code p0300 & p0304 . I'm thinking I mixed the connectors ? I'm not sure please help

[@ERICSDIYGARAGE]

yeah go back and check your connections

[@illuminatethevoid]

U have bad coil packs

[@alias6811]

Yea not just rear wheels drive cars I got 2005 g35X awd sedan and this is the same process but getting that shoring harness out the way on the passenger side it’s Baddd lmao

[@nishanthananth9668]

This is way easier than replacing the spark plugs on a nissan tiida 🤣🤣🤣

[@patrickmartin8678]

When torque the spark plugs down to spec, are you using inch pounds? Or foot pounds?

[@ERICSDIYGARAGE]

foot pounds

[@Justin-hz8bh]

How many foot pounds? Not clear which number to go by in manual.

[@jenningswest79]

I put my Infinity G35 coupe on the computer says cylinder Force misfiring code brought up the code PO304 I'm not a mechanic otherwise I wouldn't be watching videos LOL but I have done a lot of work to my car because of videos just a quick question should I start with the spark plugs and the injectors first cuz I know it can get worse than that as far as more money if it's something else might check engine light was flickering off and on and then finally stayed on all in the same day? Any information would be great

[@ERICSDIYGARAGE]

Start with your spark plugs if it doesn't go away move the coil park to another cylinder if the code comes up with the cylinder number that you moved the coil pack to than it's a bad coil pack if that doesn't work it could be a bad injector

[@jenningswest79]

@@ERICSDIYGARAGE thank you man I appreciate the response quickly you just got yourself a liking a new subscriber awesome video too because it's more up close I can see what you're doing actually compared to a lot of the other videos with the cameras away from it to see what they're doing so I appreciate your video and I'll keep watching them thanks a lot again!

[@BrandonGonzalez-vc7lu]

🐐

[@p1mpjunior12]

Nice tutorial. That whole noodle hose on the spark plug kinda baffled me... A wiggle and an extension seem like a better option just becareful as you drop the plug down because with that noodle or an extension you'll still damage the plug with a good enough smack

[@ERICSDIYGARAGE]

The issue with sockets is that over time they wear out and the rubber part or metal part that keeps the spark plug from falling ends up failing and they stop working this is going to work all time in my opinion

[@DropDeadAuthor]

I did this but my engine light came on, everything is connected properly so I don't know what could be the issue.

[@B86RZ]

Coil packs are bad

[@brooklynknightss]

It's there a rubber gasket over the spark plugs?? Or rubber gasket around the spark plugs?? Thanks!!

[@ERICSDIYGARAGE]

The gasket for that is built into the valve cover and is not serviceable if leaking

[@YoungHurricane]

Use a spark plug socket. No extra magnet. The magnet is built into the socket 👌🏾

[@adammarron3085]

Yes but with wat do I torque it with?

If you change the spark plugs do you have to change the ignition coils?

[@ERICSDIYGARAGE]

No

[@frankvasquez4291]

If u have the money just go ahead and replace those coils as well sometimes taking them off will brake them then ur stuck with a engine light and miss fire

I've never had one break on me when removing plus I don't replace things if they are not necessary the vehicle will let you know when it misfiring
