Spark plugs are one of the most critical components inside your engine that need to be maintained. There’s a decent probability you will need to replace your old and worn out spark plugs several times over the course of owning a 1995 Honda Prelude. Spark plugs are one of the most important components inside your engine as they trigger the entire combustion process that starts and keeps your engine running for many thousands of miles. Similar to most engine parts and components, spark plugs experience wear over time and eventually need to be replaced, but fortunately this is a repair you can do yourself. Odds are, if you’ve found yourself here, you have no idea how to do that, or maybe you’d just like to know what kind of spark plugs you need to buy. The entire process of changing your spark plugs should take roughly 20-45 minutes. This article will go over everything you’ll need to know about your Honda Prelude’s spark plugs, whether you need some general information or a full, step-by-step guide to performing a spark plug change.
Correct spark plugs on a 1995 Honda Prelude
How often should I change my spark plugs?
Generally, it is advised that you replace spark plugs once every 20,000 to 40,000 miles. Of course, please make sure to check your owner’s manual to determine the exact interval determined by Honda for the 1995 Prelude. Of course, if you drive your vehicle more aggressively or own a Prelude with some modifications, you may want to consider changing your spark plugs closer to the 20,000 miles end of that spectrum.
However, there are also telltale signs of a car that may need a spark plug replacement prematurely, such as:
- Problems starting your engine
- Rough idle
- Engine misfiring
Note that this list is of course not comprehensive, and these problems on their own do not necessarily point to the spark plugs being the solitary culprit. However, the best way to prevent any issues with your vehicle is to take care of it with routine maintenance, and you are definitely doing so with the responsible decision to replace your Honda Prelude’s spark plugs on a regular basis.
Changing spark plugs on a 1995 Honda Prelude
This is a process you can do on your own with some commonplace garage tools. Of course, consult your owner’s manual, as well as a factory service manual (FSM for short) or an equivalent Haynes or Chiltons manual. The video shown below does a good job of outlining the process.
Helpful Tools
- A torque wrench is a vital tool to have in your arsenal. You should check your FSM (factory service manual) or owner’s manual to determine the correct torque rating to use when putting in the new spark plugs for your 1995 Honda Prelude to be sure they are installed properly.
- A spark plug tester – this is definitely a niche tool, but it can save you a ton of time. Although we’ve discussed spark plug replacement being a good thing to replace regularly and not just when issues occur, you may also be replacing your spark plugs because of something going wrong. This tool can help you diagnose the exact problem.
- A set of spark plug sockets – These come in extremely handy because many standard sockets are not deep enough for spark plugs. In addition, some spark plug holes are a bit smaller, so it requires a thinner wall like the one featured in the product here to fit. The linked product also features a magnet to keep a good hold of the spark plug so you do not drop it into your engine bay!
- A spark plug gap tool. This allows you to check the gap of your spark plugs and increase or decrease it if necessary. Most plugs will come pregapped, but if this is not the case, you should definitely have one of these.
- I also highly recommend you have a feeler gauge as it makes it a bit easier to check the exact gap, and it is helpful for quite a few other jobs.
Tips for changing spark plugs on your 1995 Honda Prelude
- Take this (unofficial advice) lightly as many spark plug manufacturers advise against the use of anti-seize. However, I have heard from numerous old-school mechanics that they always apply a light coating of anti-seize to the threads of their spark plugs, especially on older vehicles.
- First, disconnect the negative terminal of your battery. It’s a good idea to disconnect the battery anytime you work on the electrical system of your Honda Prelude or any other vehicle.
- You should replace spark plugs on a cold engine. Wait at least 30 minutes after your engine has been running before attempting to replace the spark plugs on your 1995 Honda Prelude
- You might consider using dielectric grease when installing new spark plugs. You can apply a a little bit to the inside of the boot and the ceramic part of your spark plugs. It lessens the chance of voltage leak and helps avoid the misfortune of the boot fusing to the spark plug over time.
- One of the most important things to remember is to avoid overtightening the plugs or worse, cracking them due to overtightenting. Use a torque wrench capable of lower, more precise torque ratings to be sure that you don’t make this mistake.
