Replacing spark plugs on '08 G35
Hi,
Can somebody tell me how to replace spark plugs on a g35. I know I have to take off the engine cover, find the correct wrench, etc but is there a detailed DIY guide somebody over here has? Thanks for any help I can get here |
The stock plugs are rated to last a long time (forget the exact mileage #), so I doubt you need to change them.
|
agree, why are you changing them?
|
how many miles befor u change them on a 07 let me know plz i got 63k
|
I changed mine @ 88k because i was misfiring in cylinder 6, and that plug was just awful when i pulled it out, word of advice, get your plugs FROM the DEALER, tell them another dealer quoted you 12 dollars a plug, you'll get the price i'm sure. or if you want to be safe, i paid 12.50 for mine, one thing i encountered was after i did my plug install my ecu had tripped out, and that whole ordeal costed me 145 bucks @ infiniti to reset my ecu ;[ but other than that, the install is VERY easy intakes are easy to take off, just make sure you don't unplug any sensors especially to the throttle body.

Thanks guy for the advice. Just to answer the queries:
1] Infiniti recommends spark plug replacement at 50k miles (in my region at least) 2] eticket and Austin Are correct, the plugs do last a long while. To be honest a friend got me a set of Bosch fusions which are working a bit better than the stock densos in his g37 '08. Though I'm not missing any sparks but theoretically the extra spark your plug produces does help. This is purely an experiment. 42N81 thanks for the words on the ecu issue; will keep that in mind. Thanks again guys. Happy driving! |

Holy crap... that's complete highway robbery. :eek: |
I'm also looking to change plugs on an 08 G35 sedan rwd.Does plenum need to be removed completely?
|
I'm going to do mine in the next week or so while I have my upper plenum off. However, it is not required to remove the plenum at all. I think I paid maybe $40 for upgraded Iridium X plugs in oem heat range at Rockauto.com. Here's what I'd go by in addition to a Haynes manual I have laying around:

V36 Spark Plug DIY
I hate to plug another forum, but the best DIY I found for the 07-08 G35 Sedan spark plug change...

Plan on doing this tomorrow.
Is TB removal necessary? also off subject, is that coolant running to the TB? In AZ I don't have to worry about frozen condensation. Seems like an opportunity for a cheap mod. |
