How to replace plugs in an '07 Sentra?

[blownb310]

My question is, do I have to remove the intake manifold to replace the plugs on an '07 Sentra with an MR20DE? Seems crazy, but I see no other way. If so, will I need a new intake gasket or is the manifold O-ringed?

Thanks, Mike

According to my 09 FSM, that is the correct/only way to get to the spark plugs. You shouldn't have to replace the gasket unless it looks worn or damaged. If this is the first time opening the manifold you should be fine.

OK, thanks very much for looking it up for me. I'm sure there will be others who will be wondering the same thing when the time comes for them.

Already tried changing them no you dont need to replace a manifold gasketyou do need to take off the manifold but when i go to changing them my spark plug socket doesnt fit i tried looking to see if there was a specific socket needed but i havent found much support

when you say they don't fit, do you mean the plugs are not standard size or you can't reach them with your socket? I'm not sure sure what size they are but it's most likely 5/8

Thanks for the reply and feedback. What size spark plug socket were you using? It was a spark plug socket and not a regular socket right?

Yeah i'm a noob at cars but not that much well i been using the 5/8 and it fits on the new ones that i got thats how i know they are the right sizebut when i try to take off the ones on the engine the socket doesnt fit all the wayit gets stuck like halfways through

OK let me get this straight:

1. You can fit the socket all the way in directly onto the new plugs?2. When you put that same socket over the ones in the engine, it does not go all the way in so you cannot grip the spark plug and turn it?3. Does it look like something is blocking it if #2 is true?4. Are the spark plugs easily visible and reachable once you've removed the manifold?

Sometimes you have to use an extension on your ratchet to reach the spark plugAlso check the rubber housing inside the spark plug socket and make sure it can slip easily onto the top of the spark plug

I have read somewhere that the was the deal on some of the b14 sentras and it might be the case in my scenarioi will see if any rubber housing is blocking the way to the spark plugsThanks for the help

Think you may need a thin wall socket? Ask nico online mechanic.
