1994 NISSAN

Can you please help me with replacing my spark plugs? I have a 1994 Infiniti Q45t V8. Ive never owned a car that the spark plugs were not easy to get to and not sure how to go about replacing them.I'm very picky about who works on my car and want to make sure it's done right. We bought Boshe plugs but after reading everyones articles on here I'm not sure if I should use them.I'm traveling 250 miles Saturday morning for my family reunion and need to change them before I go. Please help me! Any help will be very much appreciated. Thank You, Paula :wink:

Chk out a service manual on the website for direction for r&r plugs. But NGK is all we will put on nissan. Thats factory replacement. Also most of the original plugs are design for 50K or more. Therefore some manifold or runner design most likely bury the plugs. It is not uncommon for other japanese make such as toyota and mazda require removal of upper intake to have acess to plugs. But it shouldn't take more than 2 hours and an ASE certifly mechanic should have no problem winging it out.
