The Lexus IS F at 18: Why Japan Still Builds Them (NOVEL and HighSpark)
The Lexus IS F came out for the 2008 model year. That makes it 18 years old, and I still think it's one of the most important cars Lexus ever made. It's where the 2UR V8 story started. Everything that came after, the RC F, GS F, IS 500 and LC 500, traces back to this car.
So let's talk about why people still build them, in Japan and here, and how NOVEL and HighSpark fit in.
Why the IS F still matters
A compact sedan with a naturally aspirated V8. That formula is basically gone now. Toyota and Lexus spent over a decade refining the 2UR into the bulletproof engine it is today, and the IS F was the first car to get it.
And there is something to be said about wide open throttle in a naturally aspirated V8. You can't really get that from a new car anymore, at least not in a package this size.
The biggest takeaway: build it to last
At 18 years old, the IS F build conversation is different from a new car. Reliability comes first. Then you add the parts that make it feel special.
Step 1: Coils
On a car this age, if the coils are original or you don't know their history, this is the first thing I'd do. HighSpark sells their Lexus V8 kits as matched boxes of four, Standard and Premium.
Why HighSpark over stock coils? HighSpark rates the spark output at 2 to 2.5 times more powerful than an OEM coil, and they stabilize the voltage coming out of the coil, so the engine runs smoother and more stable. What you'll actually feel is throttle response. It's sharper. Now, I want to be honest here. This isn't a big horsepower part. Better combustion efficiency gets you a small gain in low-speed torque and horsepower, but it's minimal. The real win is response and a smoother-running engine.
So what's the difference between Standard and Premium? Standard is built for the street and the occasional track day. Premium is the track-focused tier, which HighSpark tunes to raise voltage starting at idle without giving up throttle response. Going by my own notes, that's about 25% better response and 7% less noise than Standard. Both are built the same way, with German copper wire and Kyocera resin. If it's a daily driver, Standard covers it. If it sees regular track days or you're adding power, that's where Premium starts to make sense.
We cover timing and symptoms in our 2UR coil replacement post, and why they come as sets in our HighSpark matched kits post.
Step 2: Headers
The NOVEL GEN III Exhaust Manifold is still listed for the IS F along with the RC F, GS F and IS 500. Our GEN 3 manifold post has the background.
If you're working on intake too, our titanium intake video is a fun watch for IS F owners:
Step 3: Brakes
An older car deserves fresh brakes, especially if you're adding power. NOVEL makes a 2 piece front and rear rotor kit for the IS F with aluminum hats, and a front and rear pad set.
Step 4: NOVEL carbon
NOVEL's IS F carbon is handmade in Japan, and much of it comes from their Nürburgring and VLN endurance experience:
The cooling bonnet is my favorite. It's vented to move air through the engine bay, which makes a lot of sense on an older V8 that sees heat. And it looks fantastic.
Honest concerns
- Age. Bushings, mounts and fluids may need attention before mods. Have a shop look it over.
- Availability. Some IS F parts are limited stock. Ask us before you plan around a date.
- Emissions. Know your local rules before headers.
Why we keep supporting it
Honestly, because IS F owners keep calling. It's a car people hold on to. As long as owners keep driving them, we'll keep bringing in the parts from Japan that keep them sharp.
Buying a used Lexus IS F today: what to check
A lot of people calling us about the IS F just bought one. At 18 years old for the earliest cars, every IS F has its own history. Before you spend money on mods, here's what we'd look at:
- Service records. The 2UR is tough, but it still wants regular oil and fluid service.
- Ignition. Original coils on a high mileage car are worth planning around. A misfire under load is the classic sign.
- Plugs. If nobody knows when they were done, assume they're due.
- Brakes. Check rotor condition and pad life. Older cars often need both.
- Rubber parts. Bushings, hoses and mounts age with time, not just miles.
- Previous mods. Know what's already been changed so you don't buy parts that conflict.
IS F fitment gotchas
The IS F looks like the regular 2IS IS 250 and IS 350 from a distance, but the body parts are different. The bumpers, hood, fenders and rear are IS F specific. So a part for the IS 350 is not an IS F part, even if the listing photo looks close. On the engine side, the IS F shares the 2UR family with the later F cars, which is why the NOVEL GEN III manifold is listed for the IS F, RC F, GS F and IS 500. Always read the model on the listing.
Install notes and difficulty
- Coils: easy. Take care with old connectors, they're brittle by now.
- Headers: hard. On an older car, expect stubborn hardware. Use a shop with 2UR experience.
- Brakes: medium. Bed in new pads and rotors properly.
- NOVEL cooling bonnet and carbon: medium. Test fit everything, and expect to adjust hood alignment.
Maintenance on an 18 year old performance car
Building an older car is different from building a new one. You're not just adding parts, you're taking care of a car that has already lived a life. We'd budget a little for surprises every time the car is on a lift. Replace worn rubber when you find it. Keep the cooling system healthy, because the 2UR makes heat and older hoses don't love that. And drive it. Cars that sit tend to develop more problems than cars that get used.
Street car, track car, or keeper?
We see three kinds of IS F owners. The first drives it every day and wants it healthy and a little sharper. Coils, plugs, brakes and maybe an exhaust cover that. The second takes it to track days. That owner should put brakes and cooling much higher on the list, then headers. The third sees the IS F as a future classic and wants to keep it close to original, with tasteful Japanese parts that could be reversed later. All three are good ways to own this car. Tell us which one you are, and we'll shape the plan around it.
What other IS F parts we see owners pair
Beyond NOVEL and HighSpark, IS F owners often look at LEMS Japan for detail parts, like the LEMS titanium intake pipe for the 2008-2014 IS F. Titanium and carbon parts suit this car well, because they feel like the special editions Japan builds.

FAQ
Does the NOVEL GEN III manifold fit the IS F?
It's listed for the IS F, RC F, GS F and IS 500. Check the product page for your year.
Should I replace the coils on my IS F?
If they're original or you don't know the history, a matched set is cheap insurance.
Is the NOVEL hood functional?
It's a vented cooling bonnet designed to increase airflow through the engine bay.
Are NOVEL IS F parts in stock?
Some are in stock in Ontario, California and some are limited. Ask Tania or Kenia.
Do HighSpark coils add horsepower?
Only a minimal low-speed torque and horsepower gain from better combustion. The real benefits are sharper throttle response and a smoother engine.
Do IS 350 body parts fit the Lexus IS F?
No. The IS F has its own bumpers, hood and fenders. Buy parts listed for the IS F.
Is a high mileage IS F worth building?
It can be, if it's been maintained. Start with reliability, like coils, plugs and brakes, before adding power.
Are IS F parts still available?
Many are. NOVEL, HighSpark and LEMS still list IS F parts. Stock changes, so ask Tania or Kenia about what's on the shelf.
Next step
If you're putting a plan together, the easiest thing is to add the parts you're looking at to your cart and hit Add to Quote. We'll look it over, confirm fitment and availability, and get back to you. If you'd rather talk it through first, reach out and Tania or Kenia can help with fitment and stock questions. No pressure at all. We'd rather you buy the right part once than the wrong part twice.
